We have a variety of products ranging from Cold Binding Adhesives, Wet & Dry Lamination Adhesives, Pressure Sensitive Adhesives, Side Sealing Adhesives, Bottle Labelling Adhesives, Jelly Glues, Wood Working Adhesives, polymer emulsions for Paper Coating, Construction Chemicals, Paints & Textile applications; Our products come with the brands like Veetac, VeeCoat, Veecure, Teebond etc; Our products are known for their high quality and high performance at the market; they are now well established in both the large industries as well as the small & medium establishments in India.
BACKGROUND OF THE INVENTION
Resins and catalysts not only present health and safety issues within the factory or worksite, but they also present issues within the community relative to the release of volatiles and waste disposal. These materials could be toxic or flammable, or they could be skin irritants. These raw materials should be compounded in a safe environment. Once formulated, the end user also has responsibilities with regard to safe handling and disposal of adhesive and sealant products.
Most liquid resins can be mild to moderate irritants to the skin, eyes and mucous membranes. The irritant potential is increased by their sticky nature, which tends to lead to prolonged skin contact. These resins are generally mild-to-moderate dermal (skin) sensitizers in susceptible individuals. Resins that are modified by the addition of reactive diluents or solvents are more serious irritants. Their sensitizing potential tends to increase with decreasing molecular

weight. Components with significant volatility cause irritation to skin, eyes and the respiratory tract.
Amine curing agents, for example, generally irritate the skin and eyes. They are also considered to be strong caustics and will produce serious local injury on short exposure. Their fumes pose additional hazards in hot work environments. Reactive curing agents are generally more of a health hazard than unmodified resins. Catalytic-type curing agents are difficult to generalize because of differences in chemical makeup.
In a two-component product, the resin and curing agent are packaged separately and must be mixed together just before use as each component can be hazardous. In a single-component product, the resin and curing agent are supplied in pre-mixed form.
Solid adhesives, such as powder, preforms or film, are the least toxic because they have very low vapor pressures, they may still present a hazard when heated to a more volatile state to cure.
There is no medical or laboratory test that can quickly measure the amount of a foreign material in the human body, and most of the chemicals found in adhesive and sealant systems are not stored in the body.
There are different types of glue adhesives which takes minutes or hours to set properly and not easy to use. Many adhesives are expensive and takes a lot of time to make use of and also gives end result not too smooth.
Textile chemistry is a highly specialized field and it applies principles of chemistry at different levels of textile and apparel manufacturing. Textile chemistry includes many segments and not every textile company can do it on their own due to consumer demand for enhanced quality and functionality in market.
In market one may find many options in the field of wood working adhesives but mainly you
may come across problems such as:
a) Poor Penetration: usually to cut the cost of making adhesives for wood, people make low quality of adhesives which has different porosity and the sizing of substrate isn't proper.

b) Poor matching usually results to a compromised product by using the wrong adhesives. Both nationally and within certain individual states, rules governing use of adhesives and sealants are aimed at maintaining air quality. These laws are in effect because certain volatile organic compounds (VOCs) adhesive and sealant products react with nitrogen oxides in the air in the presence of sunlight to form the ozone and subsequently pose a health threat in the lower atmosphere by causing respiratory problems.
As for the other materials used in shoe manufacturing, the selection of the adhesive to manufacture the adhesive joint is very important to ensure a good quality and durable final product. The use of adhesives in the footwear industry is a constantly evolving process, always guided by advances in chemical knowledge and methods. Nitrocellulose adhesives were among the first to be introduced, as far back as 1906. The adhesives were mostly replaced in 1949 by polychloroprene (PCP) adhesives due to their versatility, as they present good results in bonding leather, textiles and other materials, such as vulcanized rubbers. The introduction of plastic materials to the footwear industry containing high amounts of plasticisers made necessary the search of alternative adhesive, with these anti-adherend plastic substances. For that reason, in 1970 adhesives based on thermoplastic polyurethane were introduced and we make use of this adhesive for shoe making. Lately, there is a strong requirement for the replacement of solventborne adhesives in order to improve workers' health and avoid environmental concerns.

We Claim,
