Fevicol type adhesives come under the category of synthetic resins and latex adhesives are made from polyvinyl acetate is a thermoplastic, odourless, tasteless, non-toxic, essentially clear and colourless resin. . It has a non-crystalline and relatively branched rather than linear structure. Most grades of resin have a somewhat broad molecular weight distribution. They do not melt, but soften over a temperature range. The resin is unaffected by sunlight, ultraviolet light and air, furthermore it will absorb a small amount of water. Polyvinyl acetate is neutral and non-corrosive. Because of their relatively low cost, ready availability, wide compatibility and excellent adhesive characteristics, many polyvinyl acetate resins, solutions and emulsions are treated as commodity items by the adhesives industry. Although loosely referred to as an emulsion, the product is not a liquid/liquid system, but mainly an aqueous dispersion of swollen solid particles. Uses and Applications A synthetic resin substitute for hide glue is called polyvinyl acetate. These adhesives are adaptable to high speed machinery in paper conversion and packaging fields and find place as wood adhesives Polyvinyl acetate is now used in adhesives for various application including the following :-book binding, paper bags, drinking straws, envelopes, gummed tapes, folding boxes, multi - wall shipping bags, labels, film and paper boards, foils decals, cigarette tips, wood assembly, padding automobile, upholstery, pencils, leather binding, tile cements etc. The vinyl acetate adhesive is also used for lamination; combination of two or more plies of material into a new composite. Market Survey Strong construction activity in recent years has boosted consumption of flooring adhesives, nearly all of which are water-based. Other larger formulated water-based construction-adhesive applications include glass insulation, and paper and vinyl wall coverings. Cementitious polymer additives are 13% of the construction-adhesive volume. These polymer products serve to modify the physical, bonding and application properties of cement-based products. Exterior-insulating and finish systems (EIFS), ceramic-tile mortars and grouts, flooring underlayments, concrete-repair products, and bridge decks are outlets. Applications where water-based adhesives are classified as binders are wallboard-joint compounds and cellulose-insulation products. Both applications are mature. Packaging is the third-largest end use in both volume and dollars, capturing 10% of the weight and 17% of the value. Water-based technology dominates in packaging, and a sluggish 1% annual rate of growth is forecast. Growing substitution of plastic packaging, which uses no adhesives, and the slight trend to hot melts, are negative growth factors for water-based adhesives. The manufacture of adhesive from synthetic resin is simple and can be started with a very little investment. The most advantageous factor in this plant is that it can be switched over to any type of adhesive as per market demand. Few Major Players are as under:- Advanced Adhesives Ltd. Anabond Ltd.
