properties, the application of this Boron-based chemical is
preferably used as a preservative, fungicide and corrosion inhibitor.
This compound, complex in nature, is utilized by several
industries for variety of purposes and needs. It is widely popular
for its use as a fire retardant in PVC, Polyolefin, Elastomers, Epoxy
Resins and Polyamides. This chemical is also used in
Halogen-containing systems in conjunction with Antimony Oxide,
whereas in Halogen-free systems, it is used in combination with
Alumina Trihydrate, Red Phosphorous and Magnesium Hydroxide.
So
when we talk about its uses in our everyday life, this Boron-based
chemical is used to serve the needs of various products and objects
that are manufactured in the industries. As in most of the polymer
compounds like canvas tents, Zinc
Borate
diffuses water of hydration at temperatures above 554 degrees
Fahrenheit to restrict fire and suppress smoke.
In furniture
industry, it serves as an excellent chemical for the treatment and
protection against termites and other corrosive insects in lumber,
wood, hardwood and plywood. Thus constitutes in the longer life of
wood due to its preservative properties. At the present time, borates
based chemicals have become an important ingredient in different
kinds of ceramic tiles and enamel glazes to enhance durability and
improve luster.
Due to such amicable and revolutionary
properties, borates-based products are now required in almost every
industry for assorted reasons and needs. As a result, companies have
now ventured in to producing such chemicals and clays that increases
output and decreases energy consumption of manufacturing industries.
They supply these Boron-based chemicals to their clients with optimum
quality and industry standards.

Industrial and Household Uses of Epoxy Resin
Epoxy, a form of resin, is recognized as an extremely durable glue type, which renders top-notch level of bonding properties. It is usually sold in 2-different packages known as Part A (resin) and Part B (hardener). It is important to blend both the parts in exact ratios before utilizing them to avail a specific strength. This adhesive can securely bind numerous materials like plastics, wood and metals. These adhesives provide solid bonding properties and can serve as a tough layer of protection as well.
Industrial Uses
The rudiments of epoxy can be derived from petroleum products, one being Bisphenol-A, which provides this chemical its boding efficiency. Another component in this resin is Epichlorohydrin that aids the chemical and provides a strong layer, which is resistant to moisture, humidity and an array of varying temperatures.
The qualities like strong bonding and hard coating make these adhesives a perfect choice for thermosetting epoxide polymer to be utilized with metals, which undergo great levels of stress. Some instances of such applications are, metal plating on ships and hulls of airplanes. The versatility of these adhesives facilitates it to be utilized even in the construction of wooden furniture. In this application, this hardener is able to secure sections of frames and acts as a coat of protection when it is utilized to varnish the finished product. Varnishing utilizing epoxies render the product an alluring finish and are highly potent to sustain that eye-catching look for many years.
Household Uses
Moreover, you can utilize these resins to repair defected household products. For instance, if the leg of a chair has begun to wobble, you can apply this adhesive to secure the joint.
It acts as a hardener, which creates robust joints and renders it with durability to endure any amounts of stress that it may undergo.
Some other applications of this hardener in household includes repair of broken clocks, antique picture frames, making candles and components that might have fallen off from a device. These chemicals serve as an effective substitute to any other forms of glue, which you might be utilizing to repair household stuff.
When using this hardener, keep in mind to mix the vital elements (as instructed on the pack) before applying it to the components. Different brands of epoxy come with different time limit, like, how much time is required for the chemical to dry up and provide a sturdy bond.

Being one of the several varieties of water insoluble dyes, this
dye has revolutionized the textile industry with its coloring
capabilities. The dye is used to color the fiber only after changing
it to leuco form in an alkaline solution of sodium hydrosulfite.
These dyes are classified in four categories depending upon the
degree and amount of temperature, salt, caustic soda and hydrosulfite
are required.
The four main categories of VAT Dye is IN Dyes,
IW Dyes, IK Dyes and IN Special Dyes in which the ingredients and
compositions varies from high, medium to low. Vat dying holds several
benefits; among them, long lastingness, wash fastness and light
fastness are the eminent ones.
In textile industry, dying
fibers with Vat
dyes involves multiple stages and processes, such
as –
To change the insoluble pigments of Vat dyes into sodium leuco-vat anions that is more soluble in nature
The sodium leuco-vat anions are then dispersed in to cellulosic fibers
Wiping off reducing agents and excess alkali through wash mechanism
Oxidation of soluble dye into insoluble pigment form that are within the cellulosic fibers
At the end, the leftover molecules are reoriented in to more crystalline form through soaping
Looking at the above mentioned processes and multiple
stages in the procedure, it seems to be complex and intricate;
however, when one sees the final output, it is amazingly bright and
shiny. The results mainly depends upon the procedures followed at
different stages and out of all those stages, reduction is the most
important one whose success is based on factors like particle size of
the dye, time, temperature, pH of dye and the concentration of the
reducing agent.
Vat dyes possess unique benefits and due to
their distinctive properties, they have found their utility and
usefulness for wide range of fibers like wool, rayon, cotton and
several different varieties that are used in textile manufacturing
industries. Their coloring aspect and long lastingness is highly
popular to bring different shades of bright colors to the fibers.
VAT Dye has become the most important part in every form of
dying requirements in the textile industry due to its excellent
results and ease of availability. There are companies that deals with
such coloring solvents and dyes primarily for variety of industries,
variety of purposes. These companies manufacture chemicals for

Basic dyes belong to the class of synthetic dyes and are from the
family of aniline dyes. These dyes are called so because they are
salts of organic bases. They are also referred to as cationic dyes
because in solution these dyes molecules ionize, causing its colored
components to turn into an action of positively charged radical.
Generally, these dyes are considered very easy-to-use and they can be
used in several of printing and dyeing tasks. They feature excellent
tinctorial strength and great brilliance, both of which are not at
all excelled by any other category of dyes.
Properties:
The characteristics that make these dyes special are the intensity and brilliance of their colours.
They are readily soluble in mentholated spirit and alcohol
Many of these dyes are hardly soluble in water.
The major property of these dyes is that they will fuse with tannic acid to form an insoluble compound, provided mineral acid is not present.
These colorants have poor fastness to light and differ in regard to washing fastness from poor to moderate.
The wet fastness of these dyes on protein fibres can also be enhanced by means of back tanning. This includes treating the dyed material with tannic acid to form the insoluble compound, thereby alleviating the tendency to migrate.
Materials like cotton are regarded as inadequate substrate for these dyes because they do not possess the entailed planar structures to absorb dyes.
Most of these dyes are chlorides by chemical combination and they have positively charged colouring agent (or chromospheres).
Majority of these dyes have vivid colours with varied range of brilliance. Besides, they may exhibit fluorescent properties and may occur in different colours.
Special cationic dyes are also available for dyeing acrylic fibres.
These dyes are utilized for woolen materials when particularly vibrant shades are required that cannot be obtained with acid dyes.
Applications:
Applications on wool, paper, wood,
feather, straw-braided articles, leather and cotton is recommended.
Selected members of this category can also be utilized for printing
or dyeing on polyacrylonitrile fibre and acetate fibre.
Furthermore, the freebases of these dyes can be utilized as
solvent
dyes.
Pigments precipitated by the combination of these dyes with
phosphotungstomolybdic acid, display high fastness to light. They are
extensively utilized in the manufacturing of stationery items like
stamp-pad inks, carbon paper and ball-pen. In addition, these dyes
can be employed as colouring elements in distemper when precipitated
in China clay.
Cationic dyes are economical as compared to the other dyes.
These dyes are extensively known to produce some of the best
synthetic dyes utilized for commercial purposes. These dyes are a
popular choice for their usage in hand painting on acrylic fibre
because they are bright in colour and have a wash-fast property, when
utilized on acrylic. They are also utilized for permanent dying of
containers, floors, sinks, counters and wide array of other
materials.
Basic
dye
is reliable and has strong colorants having numerous commercial
applications. To know more about basic dyes and its properties, log

The epoxy adhesives are primarily a group of high-performance bonding agents, which include polyurethane, acrylic and cyanoacrylate among others. The differences among the various kinds of these adhesives mainly depend on their utilization purposes. The variations are done with the aid of hardeners that can make these adhesives opaque or transparent. These adhesives can be utilized to bond anything – steel, wood, glass, stone and even aircraft and boats parts.
Clear Epoxy Glue
This glue is an adhesive mostly utilized for industrial applications. It is made up of two-parts i.e. liquid and powder. The proportions of these two-parts depend on your requirement like, how tough and swift to dry adhesive is required? One of the important industrial uses of this glue is in the jewellery industry, particularly, jewellery made out of plastic. In addition, this clear glue is utilized on large-scale for bonding of wood, glass and steel among other materials.
Clear Epoxy Resin:
This resin is also an adhesive, but it is utilized as super-high gloss. A single coat of this resin equals as many as thirty coats of regular varnish. This is why these resins are utilized for the final touches on almost anything – stone, clocks, leather, plaques and ceramics etc. These clear resins are ideal for polished surface bar counters and tabletops.
Clear Epoxy Glue vs. Clear Resin –
Difference in their Uses
The fundamental difference between Epoxy Glue and Clear Resin is their application or utilization. While the clear glue is usually utilized to bond products on small and large-scales, the clear resin is utilized more like a last finish coat, which enhances the appearance of the product. The clear glue can easily be manipulated by adjusting the proportions of the liquid hardener and powder epoxy into an adhesive, which dries slowly or swiftly, turns elastic or hard or into moulds for making plastic models. The resin is utilized to make a super-glossy, glass-type finish on any item – usually stone or wood.
Difference in their Application
The clear glue, though a brilliant adhesive, which can be utilized to bond any kind of surface, is just an adhesive. However, clear resin also protects the surface it coats from rot (the chemical properties of this resin facilitates it to mingle in woods while it bond to it; hence, making it fungus proof), from water (it is water repellent) and from scratches (it hardens to turn into a glass-type surface).
These were some of the major differences between clear epoxy glue and clear epoxy resin. For more information, log on to www.royceintl.com.
Whenever the discussion of Basic dyes starts, the very first
sentence is often, “they are colored aromatic compounds.” These
dyes are water-soluble cationic dyes that are primarily applied to
acrylic fibres, but find some usage for silk and wool as well. These
dyes are highly praised for their ability to produce brighter colors
on textile. There are extremely bright dyes, which are commonly
synthetic.
Basic
dyes
are named so because they are organic bases or salts, and are
referred to as cationic dyes because in solution the dye molecules
ionizes, causing its colored element to turn into an action of
positively charged radical.
Properties:
The amazing properties of cationic dyes are intensity and brilliance of their colors
Many of these dyes are meagrely soluble in water
These dyes are readily soluble in mentholated spirit and alcohol
One important property of these dyes is that it can combine with tannic acid to create an insoluble compound provided mineral acid is not present.
When treated with a reducing agent, most of these dyes are converted into their colors less leuco compounds, which can return to their original shade via oxidizing agents or exposure to air.
The wet fastness of cationic dyes on protein fibres can be enhanced by back tanning.
The brightness and quality of colors obtained with these dyes are amazing and unparallel
It is advised not to use these dyes on cotton owing to the non-plainer structure of cotton and its incompetency for sufficient affinity.
Uses of cationic dyes:
The dyes are utilized for wooden goods when specifically bright colors are needed that cannot be availed with acid dyes
They are used for making typewriter ribbons, inks and dyeing leather.
Basic dye does not possess affinity for cellulosic fibres like cotton. However, bright shades are required on cotton that can only be achieved by using cationic dyes.
They are applied to silk, modified acrylic fibres and wool
They are used for coloring dry flowers, cut flowers, coir and jute.
Are used for coloration of paper
Modified Basic Dyes
The all-new improvised dyes, based on
an identical chemistry of cationic dyes, display a bit lengthier
molecular structures as compared to conventional cationic dyes, and
results in substantially improved properties. Their key benefits over
conventional cationic dyes are:
Outstanding substantivity
Covers all fibres
Better Light fastness
Clear backwaters
In case, the reason behind the success of basic dye is
assessed, it would be noted that the positively charged cations of
these dyes becomes attracted towards the negatively charged anions in
the acrylic fibre. Some major examples of cationic dyes are basic
fuchsia safranin, crystal violet and methylene blue etc.

Use Epoxy Resin for Fine Adhesion and High Stability
Epoxy,
along with its incredible range of applications, has been extensively
used since 1950s. Many books were written about these adhesives and
its usages in the 70s, but since then myriad changes have happened
in, both, its formulation and uses. As of 2011, the epoxy
resin
industry amounts to over $15 billion in North America and about $25
billion across the world. In the current times, epoxy users have
become highly sophisticated and expect more from these adhesives for
which they spend their money.
Overview
These
adhesives are thermosetting polymer created from the reaction of
epoxide 'resin' with the polyamine 'hardener.' These resins are used
in a range of applications, including general use adhesives and
fiber-reinforced plastic materials. Furthermore, they are a class of
synthetic resins commonly utilized to make adhesives and plastics.
They are highly acclaimed for their splendid adhesion, toughness,
durability and high- resistance to heat and chemicals.
Applications
Functions
of these resins are fundamental across numerous industries – it is
used in glues, ad infinitum, putties and paints.
Paints
and Coatings
Two-part
epoxy coatings were formed for heavy-duty employment on metal
surfaces and utilized less energy as compared to heat-cured powder
coatings. They dry swiftly providing a durable protective coating
with outstanding solidity. Their low volatility and easy water
clean-up makes them bulls-eye for factory cast aluminum, cast iron
and cast steel. They are widely used in automobile and industrial
applications because they are more heat-resistant as compared to
alkali-based and latex-based paints.
Foams
Epoxy
resins are utilized to form lightweight, sturdy, foamy structures
boasting of excellent insulation properties. Moreover, they are
specifically utilized for foam-in-place applications in the casting
and 'potting' process. These resins are produced either by blending a
prefoamed filler in the liquid system or by a chemical reaction.
Construction
These
resins are now utilized as binders in materials employed for
construction. Typically, a 2-parts system consisting of diluents,
thickening agents, fillers, curing agents and resins is used. They
are utilized to bond concrete and to generate industrial smooth
slender-set terrazzo floors. This application has been extended to
the construction of buildings, roads and filling up the cracks in
concrete structures.
Adhesives
The
versatile characteristics of these resins make them extremely
valuable as adhesives in military and civilian applications.
Approximately 5% of total epoxy production is consumed as adhesive in
a range of structural applications. These adhesives create strong
bonds with all kinds of surfaces, with the exception of some
non-polar surfaces.
Laminates
Laminated
epoxy based insulations are widely utilized as rods, tubes and
sheets. Paper, polyaramid fabric or sheets of woven glass with the
B-stage epoxies are laminated in multiple pattern presses. In
addition, they are utilized in preparing assemblies of polyaramid
fibers or copper-clad glass for printed circuit boards in the
electronics sector.
These resins can be bought from hardware
store, marine supply outlets, hobby shops, craft stores or online.
However, when using epoxy resin, it is essential to follow certain
safety measures. A person must work in a well-ventilated area and
prevent inhaling the fumes of the product. He should also wear gloves
and shades to protect his skin and eyes.

Epoxy,
also referred to as poly-epoxide is a thermostatic polymer formed via
a reaction of a polyamine “hardener” with epoxide “resin”.
This chemical compound is a co-polymer; that means, it is formed from
2-different chemicals, and they are referred to as resins and
hardener. This chemical compound boasts of a gamut of applications,
including general purpose adhesives and fiber-reinforced plastic
materials.
Application of Epoxies: Listed below are some of
the major applications of it:
Adhesives:
Poly-epoxide
adhesives are an eminent part of the class of adhesives known as
'engineering adhesives' or 'structural adhesives'. These
high-performance adhesives are utilized in the construction of
automobiles, aircraft, snow boards, golf clubs, boats, skis,
bicycles, and other applications, where high strength bonds are
needed. These adhesives can be formed to suit almost any kind of
application. Moreover, they are exceptional adhesives for metal,
stone, wood and some plastics.
Coatings and
Paintings:
Two-part waterborne epoxies coating are utilized as
ambient cure coatings. These non-hazardous, two part coatings are
created for hefty duty services on metal stratum and make use of less
energy as opposed to heat-cured powder coatings. These systems make
use of a more luring 4:1 by volume mixing ratio. The coating dries
swiftly rendering a tough, solid, UV resistant, projective coating
along with immense hardness and excellent abrasion and mar
resistance. They are designed for quick dry protective coating
applications.
In addition, ambient part two waterborne epoxy
coatings offer superior physical proper; they have superlative
adhesion to several metal substrates. Their water cleanup and low
volatility indeed makes them an ideal for factory cast aluminum, cast
iron and cast steel applications and decreases flammability and
exposure issues associated with solvent-borne coatings. They are
utilized for automotive and commercial uses since they are high-heat
resistant.

Color Concentrate - Fast Becoming a Major Priority for Many
Before going any further, let us get to
know what exactly a Color
concentrate
is. It is a plastic compound with a soaring percentage of color and
it is then blended in a right amount along with base resin, in order
to have a final color. Well, in most of the cases, these color
mixtures are often a late addendum, let us try to find as why it
actually happens.
It has been found that every now and then
various product managers, owners of the shops and engineers are
mainly concentrated towards the fresh product cycle and involved in
the evaluation of the whole process of the development of the
product. The extent of concentration is so high that they tend to
forget the influence color concentrate makes in the whole process of
product through process.
Various factors like selection of
the material, making different decision, sampling, marketing, and
building of the tools, these are some of the important ones for the
process of product making. However, in addition to this there are
various other factors, which should be considered.
Taking
early decisions for Color concentrate
It is very important that
these blends be considered in the product making process because one
never knows as when an unforeseen limitation takes place. There have
been instances in the past where the makers of the product have to
face discomfort seeing the color disappointment. It is always
advisable to keep a check on those who are proficient enough to
deliver what is promised.
Keeping in mind the shrink element
and cost modeling, the selection of the material prior to the making
of the tool should be done, and most of the times the color element
is neglected, which should not happen. There are some colors, which
are not reasonable enough in some resin systems and during the
designing of the product.
Points to be followed
During the
final choice of the concentration of the color, various factors like
certification, selection of material, temperature, conditions for
molding and exposure of environment should be considered. Here is a
perfect instance where a particular type of legislation stating an
exact color for the process of recognition reasons with no role of
engineering. It can be said that the color blends were not given much
importance prior to picking bright colors. This is a major reason for
concern for all those who were a part of making of the product.
In
the end, it could be said that the Color
concentrate
should be used in the initial stages of the making of a product.

Epoxy Resin – a Material for Stronger Bonds in Industrial and Commercial Uses
True said, “The strong bond of love is a driving force behind
many socio-economic concepts”, but in practical terms, one cannot
affix bridges and dams with love, it has to be a strong adhesive,
chemically mixed in other important elements. This strong adhesive
chemical is known as Epoxy
resin.
There are two main
categories of epoxy resins, which are termed as -
Glycidyl epoxy: to prepare these resins, there is requirement of a condensation reaction
Non-glycidyl epoxy: to form these epoxies, a preoxidation of olefinic double bond is required
These two types are further classified in sub categories as:
Glycidyl epoxy has two classifications such as glycidyl ester and the second one is glycidyl amine.
Non-glycidyl epoxy has two classifications aliphatic and the second classification is cycloaliphatic.
In chemical forms, Epoxy resins are defined as a particle,
which contains more than one epoxide group, and these groups are
known as oxirane or ethoxyline. This scientifically researched
chemical is widely used for many purposes such as in the
construction, for the purposes of home repair and maintenance and in
some instances this is also used by metal working industries.
However, epoxy based resin is not along competent enough of
holding the bond; another catalyzing agent is blended with this resin
to harden the resin into a tough adhesive. This particular adhesive
has many unmatched properties and those qualities make this adhesive
a versatile chemical.
These thermosetting polymers are
basically used for high performance coating, encapsulated material.
As these resins are blessed with laudable electrical properties,
adhesive adaptability with various metals, free from any worry of
shrinkage or moisture; hence they are used widely by marine product
manufacturers. Below are few common uses of Epoxy Resin
If you are about to paint your walls or windows, use this with your paint and colour protector.
If your little kiddo broke an expensive piece of China, let his adhesive help you in fixing the same.
You must have seen jewellery items like necklace, earring, bracelets, but do you know even jewellers use this chemical to fix the joints.
As we earlier discussed epoxy resin is moisture proof, so mainly boat owners and makers, use this resin to protect their boats (livelihood) from leakage.

Phenalkamine: A curing agent of Epoxy Resin
Epoxy Resin, which is
commonly termed as adhesive, is becoming an imperative part of
today’s construction and manufacturing sector. The primary reason
behind their increased use is its attribute that allows them to
transform from liquid to strong under a varied temperature. However,
unbeknownst to many of us, behind this transformation, there is a
formation of by-products and addition of chemically active amalgams
termed as curing agents. These curing agents are generally
derivatives of amines with Phenalkamine.
The roots of
Phenalkamine were traced in mid 1970’s when the Cardolite
Corporation (a former division of 3M Company) introduced it.
An
overview of Phenalkamine and its uses:
It comes from Cardanol.
The cashew nut shell liquid (CSNL) is the main source from where this multipurpose derivative of amines is synthesized.
In the beginning, it was brought into the limelight with a purpose to have an extended pot life with awesome flexibility and laudable water resistance.
This miraculous curing agent is a blend of aliphatic amines’ properties and Polyamides characteristics.
This system has outstanding curing property and that too on low temperature.
This curing agent has a good resistance with all sort of chemical and on top to that, the curing agent has low toxicity and high flexibility.
The most astonishing fact about it is that it is now replacing the polyamides and polyamines, the two most common and frequently used curing agents.
This curing agent comes with a water resistance property. The fact behind this water resistance is Phenalkamines’ linear side chain that provides high hydrophobicity to resins. This high hydrophobicity eventually lessens the effect of phenolic hydroxyl on water sensitivity. This is what makes it a best coating and adhesive alternate for sealant industry and for wet or poorly prepared surfaces.
This adhesion quality, which has proved its worth even on water, is the primary reason behind its use in marine applications, civil engineering and industrial maintenance projects.
Precautions:
Storage :
Must be stored in cool and dry condition: temperature must not exceed 25°C
Must be stores in a sealed container and not in open lid box, because this product can react with Co2 and moisture
Must be used within one year from the date packed
Handling
An eye contact, it can cause severe damage and inflammation
Harmful for skin, if ingested or absorbed
While handling it and while not in use, make sure that container is tightly closed
Do not miss to use safety glasses, gloves and protective clothes
In case of any misfortune, victim is advised to have first aid treatment, from a first aid attendee within the working location until the big help arrives. If you want to know more about Phenalkamine and its recommended mix ratios, please refer most helpful web portal http://www.royceintl.com/.

Dyes have been used since the prehistoric times as colorants that
have found their uses in various applications for coloring different
materials. Fabricated dyes are also termed as synthetic dyes that
have been developed ever since their discovery. Synthetic dyes are of
different types and may be classified in to basic, acid dyes, direct
dyes, mordant dyes, vat dyes, reactive dyes, disperse dyes and
sulphur dyes. One of the commonest dyes used in the dyeing of acrylic
fibers and paper is a basic dye. Basic
dyes
have a variety of uses as they are known for their vibrancy and
strong coloring abilities.
The section below gives some useful
insight about basic dyes -
These dyes are generally cationic or basic in nature and they generally react with substances (substrates) that are anionic or negatively charged in nature. They exhibit an affinity for acidic substances and that results in the formation of salts. This helps in producing bright shades on the various commercial textiles and fabrics.
Materials such as cotton are considered as inappropriate substrates for a basic dye as these do not have the required planar structures to absorb the dyes. Most of these dyes are chlorides by chemical combination and have a positively charged coloring agent or chromophore.
Most of these dyes have vibrant colors with a varied range of brightness. They may also exhibit fluorescent properties and may occur in different colors.
In the presence of glacial acetic acids, these dyes exhibit high amounts of solubility in water. However, with their low strike rate, they generally exhibit poor leveling properties.
A basic dye generally exhibits a high amount of affinity towards wool, silk and acrylic material. Materials that contain cellulose may show no affinity towards basic dye. In cases where cellulose is to be dyed, a mordating agent is used for the process.
Basic dyes are also economical in comparison to other dyes.
These dyes are known to produce some of the best synthetic dyes used for commercial purposes. These may also be used for finishing on wood by dissolving the basic dye in water and alcohol to produce beautiful multiple tones on the wood.
The slight limitations of these dyes however may include preferential dyeing and high acid content of the dye that may result in poor shade stability.
Basic
dyes
are strong and reliable colorants having many commercial
applications. Visit www.royceintl.com for further details on the

Phenalkamine – Redefining The Process Of Epoxy Curing
It is a well known fact that epoxy resins enjoy
their huge popularity because of their property of easily transforming from
liquid or even thermoplastic state into a strong and rigid thermo solid under
diverse temperatures. However, not many people know that for this
transformation to take place, epoxy resins need the additional support of a
special group of chemicals that are known as curing agents. These curing agents
are generally either amines or the derivatives of amines with Phenalkamine being the
most commonly used curing agent.
Cashew nutshell
liquid is the most common source for the synthesis of Phenalkamines. This
extremely fast curing agent is not only able to provide great results, but also
has a good workable pot life. Moreover, Phenalkamine shows good resistance
towards chemicals, has low toxicity and is highly flexible. All these qualities
make this curing agent a preferred choice for use in various marine
applications, industrial maintenance and civil engineering projects. Using this
active chemical ensures that the cured epoxy, shows good resistance to water,
is flexible enough and has great adhesive properties.
Phenaklamine is
fast replacing polyamides and polyamines which are more frequently used curing
agents as it is perfectly suitable for use with epoxy solids cured under
ambient temperatures. In fact, the name of this newest range of curing agents
has been devised to indicate the alkyl-aromatic structure of the chemical and
help people in to easily distinguish it from other more familiar polymer based
curing agents. Given the unique water resistance properties and temperature
insensitive cure provided by this chemical it is becoming an ultimate choice
for applications related to high solids or water-borne coatings.
The unique
structure of Phenalkamines provides them with a rare combination of some of the
most desirable properties, which they pass on to the epoxy resins they are used
with for curing. Though this family of curing agents is relatively new it has
already made a deep impact by providing an innovative means of enhancing the
curing process with the help of its chemically modified structure. Also given
the ever increasing market for epoxies, there is a great scope for the
utilization of this novel technology to create better products.

QMQS2 Color Concentrate – For Easy Manufacture Of Custom Colored Plastics
It is not uncommon for end-product manufacturers to seek a supply of custom colored plastic. However, fulfilling such an order is not only extremely time consuming but also quite frustrating and expensive for the plastic supplier. This is mainly due to the fact that for completing such an order, the plastic suppliers need to stop all production and clean out the machine before they can start the special production of the custom colored plastic. This is also a major reason for custom colored plastics being considerably expensive than the other plastics. However, thanks to the availability of QMQS2 color concentrate, end-product manufacturers can now produce custom colored plastics at their own end.
Given the complexities involved in producing
custom colored plastics, it is quite understandable that plastic suppliers
rarely entertain orders for small quantities, making it even more difficult for
end-product manufacturers to obtain the colored plastic. However, QMQS2
category of color concentrate helps end-product manufacturers in overcoming
even this difficulty. It enables these manufacturers to produce the required
quantity of custom colored plastic by dry blending the neat natural resins with
the color concentrate recognized for use with that resin, within the limits of
the available maximum let-down ratio. The manufacturers are free to order
sufficient quantity of neat natural resins as well as the color concentrate
that has been approved for use with that resin and produce custom colored
plastics sufficient for their needs.
The process not only proves to be cost–effective
for the plastic product manufacturers but also offers flexibility in obtaining
only the required quantity of such resins. However, it is important to have an
understanding of the use of the right color concentrate with specific base
resins and might involve the presentation of standardized test samples. These
samples generally, consist of the color concentrate let-down into the specific
base resin and are tested to ensure that the use of color concentrate does not
in any manner effect the flame rating of the base resin. In case of HB-rated
base resins, the testing involves the use of color concentrate let-down on
HB-rated base resins only so as to verify whether they are safe for use on all
types of resins belonging to this specific generic type.

All You Need To Know About Basic Dye
When
people think about dyes, the image that comes to their minds is generally of
colored aromatic compounds having the ability to ionize, making them capable of
interacting with tissue components that are oppositely charged. Dyes are
generally classified as acidic dye and basic dye depending
on the type of charge they possess. Acidic dyes are negatively charged dyes
that can interact with positively charged tissue components, while basic dyes
are positively charged and can bind themselves with negatively charged tissue
constituents.
The naming scheme of basic dyes follows a specific
pattern in which the word “Basic” is followed by the name of the base color and
a unique number. For example, Basic Red 9 and Basic Green 4 are the names of
some basic dyes. The names of the basic dyes just provide the functional and
color information about the dye and do not convey any information related to
the chemical properties of the dye. It is also important to understand that
dyes having unique names but similar numbers are not related in any manner. For
example, it is wrong to assume that basic Brown 4 and basic Violet 4 are
related in any manner.
The colored part of a basic
dye exhibits a positive charge, when the dye is dissolved in
water. They are generally very bright and washfast hence are largely used to
dye acrylic fibers. However, they are not sufficiently washfast to prove as
good dying agents for protein fibers such as wool. Moreover, in order to make
them bind with cotton fiber, the fiber first needs to be mordanted as otherwise
the dye tends to fade quickly when exposed to sunlight. The natural tannin
content of reeds, raffia, grasses and barks acts as a mordant making it
possible to use basic dyes efficiently with these materials.
Like most other dyes, basic dyes are also toxic in
nature and need to be handled with extreme care. It is vital to follow all the
safety precautions and obtain the MSDS information before purchasing any type
of basic dye. Although most companies supplying basic dyes readily provide the
MSDS information, it is advisable not to purchase these dyes from those few
companies that are not willing to give this information as it can prove
extremely hazardous to the health and safety of the buyers. It is also
advisable to buy these dyes in liquid or paste form, whenever possible.
Royce is a fully diversified international company
which was founded in 1929 to manufacture chemicals for textile industry. Today

society they belong to. The fact that mankind has been using axioms related to
various colors for ages, indicates their impact on the intellect and emotions
of humans. It is nearly impossible to think about a wide range of consumer,
medicinal, construction and even industrial products, without taking into
account their diverse colors. Given the importance of colors in human life, it
is easy to understand the significant role of a color
concentrate in adding beauty and life to a wide range of products.
Colors are largely associated with a wide range of
emotions and this often impacts the judgment of people buying various products.
Generally when people see bright and vibrant shades they tend to feel happy and
cheerful, while on the other hand, the sight of dull shades often makes them
feel gloomy. That is why manufacturers of various products, generally use a
greater amount of bright color concentrates as compared to lighter shades for
coloring their products. Colors are invariably used to indicate danger or
health hazard or even warn people about something. What’s more, for centuries
colors have been used to pass on ideas and concepts in an effective manner.
In some cases, such as in industrial products or
in the manufacture of processed food items and certain medicines, only specific
color concentrate can be used. For food items and medicines, only those color
concentrates are allowed to be used that are non-toxic and safe for consumption
by humans. For industrial products, colors generally play a greater role than
just enhancing the beauty of the products and as such specific color plans
which are in accordance with the set standards of the industry, need to be
followed while imparting color to these products.
In view of the above facts, it would not be wrong
to say that the choice of the right color has a great impact on the sales and
marketing strategies. Color is a natural way of expressing the emotions and
values of an individual, and hence its importance in products of everyday just
cannot be ignored. Therefore, for industries eager for gaining competitive
advantage in the market, it is vital to understand the psychological
ramifications of color and use the right color concentrates in their products.

Learning Some Basic Facts About Epoxy
Over the years, epoxy has been put to diverse industrial uses across the
globe. It is basically a copolymer that is created when an epoxide resin reacts
with a polyamine hardener. The resin and the hardener are also generally
referred to as the compound and the activator which when mixed in the right
proportions produce epoxy, that is put to diverse uses for industrial as well
as consumer applications. The strong adhesive properties of epoxy result from
the covalent bond formed by the reaction of amine groups with the epoxide
groups. This causes the resulting polymer to become deeply cross linked, making
it extremely rigid and strong.
The chemical structure of epoxy is such that it
can be produced in several variations each having a wide range of properties.
Often referred to by the name of magic glue, these copolymers have incredible
adhesive properties, besides showing great resistance to chemicals and heat.
That is why they are so widely used in industrial flooring. In addition,
epoxies, in general, have more than average mechanical and electrical
insulating properties.
However, the thing that makes epoxy so popular is
the fact that several of their properties can be modified and a good example of
this is the availability of silver-filled epoxies that act as good conductors
of electricity, despite the fact that epoxies are conventionally electrically
insulated. The diverse properties of these resins and hardeners make them
perfect for use in a wide variety of products including adhesives, paints and
coatings, industrial tools and flooring, diverse electrical and electronic
systems, consumer products, marine applications, art and even aerospace
industry.
The commercial value of epoxy can be estimated
from the fact that until 2006, the epoxy industry worldwide held a value of
approximately US$15 billion, with just North America accounting for more than
US$5 billion. Even though the epoxy market suffered a major setback and slumped
down to US$15.8 billion in 2009, owning to the global economic crisis, it is
again showing a positive growth and is expected to rise to the level of
US$21.35 by 2015. China holds a major stake in the manufacturing of this
copolymer with nearly 50-100 manufacturers based in the country, which amount
to almost 30% of the total manufacturers.

Understanding The Basic Differences Between Solvent Dye Inks And Aqueous Inks
Centuries
ago, the invention of printing technology revolutionized not only the method of
communication, but also the way of maintaining records. In the modern times,
the tremendous advances in printing and associated technologies enable people
to not only customize the print jobs as per their requirements but also add
additional features, which would have seemed impossible only a few years back.
However, all the developments in printing technology would prove useless, if
the right kind of ink is not used. The inks that are used for printing are
generally categorized into two types namely solvent dye inks
and aqueous dye inks.
Not many people are aware of the significance of
using the right type of ink for diverse printing jobs. They are rarely educated
about the important role played by the choice of ink in determining the
quality, clarity and durability of the printed material. Since the formulations
of both solvent based inks and aqueous inks are significantly different, they
might not be equally appropriate for use in all types of printing jobs. As such
it is vital to have some basic understanding of both these types of inks in
order to ensure that the printing job meets the specific quality and set
standards.
The basic difference between solvent dye inks and
aqueous inks lies in the carrier liquid for the ink. Solvent dye inks generally
have the carrier liquid which is derived from oil or alcohol and as such are
non-polar in nature. Such inks are generally more effective on plastic-based
materials. That is why they largely used for printing on vinyl, leather, waxed
paper, etc. On the other hand, aqueous inks have water as their liquid carrier
and work well with polar substances such as paper. Hence, the choice of the ink
largely depends on the type of material on which the print job is to be carried
out.
Even though aqueous inks have an advantage over
solvent inks, when it comes to choosing an eco-friendly ink, the latter are
largely preferred by people seeking a more durable and long lasting printing
job. However, with people becoming more aware about conserving the environment,
researchers are trying hard to develop new aqueous inks that can replace
solvent inks in terms of durability and long life. Recently, latex inks have
been launched in the market, which irrespective of being water-based provide
almost the same level of durability as solvent inks.

Polymer Colorant - Learning Some Basic Facts
Plastic is undoubtedly one of the most important inventions of human
history, which has become an integral part of our everyday lives. The term
plastic is generally used for a wide range of synthetic or semi-synthetic
products created as a result of polymerization and having the basic property of
plasticity. However, most often plastics contain other substances or additives
which help in enhancing some of their basic properties such as their stiffness,
strength, resistance to heat and flame or even resistance to electricity. Polymer
colorant is one of
the several additives used and serves the specific purpose of imparting color
to plastics.
The colorants used with plastics are primarily of two
types, namely organic colorants also known as dyes and inorganic colorants also
known as pigments. Generally, the choice of the type of polymer colorant that
would be most suitable for the plastic depends on the amount of light that the
plastic is exposed to and the service temperature of the plastic. Since
pigments show a greater resistance to both temperature and light they are used
for dying plastics that are more likely to be used in high temperature areas
where they are also constantly exposed to light. Other important factors that
need to be considered during the choice of a colorant for plastics are their
applications, level of colorfastness and reaction to base plastic material.
Today, through the use of a proper combination of
polymer colorant system, it is possible to add special effects to the
appearance of plastic. That is why it is now possible to find plastic that have
a metallic, pearlescent, stone and fleck and even thermo-chromatic and
photo-chromatic appearance. It is also vital to use the right colorant system
to ensure greater efficiency of the plastic end product. For example using
colorant systems that provide little or no X-ray opacity for plastics intended
to be used in medical applications, can render the end products useless for
such purposes. As such it is vital to pre-determine the end use of the plastic
prior to choosing the most suitable coloring option for it. Similarly, in
plastics that are used for manufacturing toys or items for household use, the
brightness and safety takes prominence over other factors.

Getting Familiar With VAT Dye
One of the most important inventions in the fields of textile dyes that were made in the 20th Century was VAT Dye. These chemically complex, water insoluble dyes need to be first reduced to the leuco form by dissolving them in an alkaline solution of sodium hydrosulfite, before they can be used for coloring various materials. The production process of these dyes is quite complex, mainly due to their complex chemical structures. That is why even though these indigo based, dyes form one of the most ancient class of dyes, they now are largely produced synthetically to meet industry requirements.
Vat dyes have a unique working mechanism and are
suitable for coloring a wide range of materials including, cotton, wool and
other fabrics. However, the application of VAT dye is much more complex as
compared to direct dyes or reactive dyes. The process is a combination of
several smaller processes including oxidation, reduction, pH control etc. It is
also important to be aware of the right quantities of caustic soda and sodium
hydrosulfite required for the proper reduction of the dyestuff.
These dyes are generally sold in the form of
pigments. It is necessary for the buyers to be aware of the dissolution and
other coloring related properties of these dyes, as these characteristics can
be easily affected by the particle size of the dye. The dyeing properties might
also be affected by the different chemical structures of the dyes, which also play
an important role in determining the stability of the dye towards excessive
reduction and excessive oxidation, its substantivity as well as its rate of
diffusion into and out of the target material.
It is possible to get vast shades of bright colors
with the help of VAT dyes. These dyes are also washfast and lightfast and it is
rare to find these properties in any other class of dyes. The one drawback that
these dyes suffer from is slightly poor rubbing fastness, which can be
controlled by applying special treatment to the target material. However, Vat
dye is not considered suitable for use for home dyers as they are slightly
difficult to work with. Irrespective of that, these dyes are preferred for
dyeing specific types of industrial yarns, terry cloth, industrial work
clothing and shirting fabrics. Moreover, they are the only dyes that do not
exhibit any serious changes in shade when exposed to topical, cellulose
reactive and flame retardant finishes.
