Nissin SOLBIN TA3 - Vinyl Chloride-Vinyl Acetate Copolymer Resin for Coatings, Inks & Chemical-Resistant Adhesives

Nissin SOLBIN TA3 Vinyl Chloride-Vinyl Acetate Copolymer Resin 1. Product Name Vinyl Chloride-Vinyl Acetate Copolymer Resin 2. Properties SOLBIN is a modified copolymer resin. It combines the toughness and weather resistance of vinyl chloride with the adhesion and plasticity of vinyl acetate. Additional polar groups are introduced to deliver excellent adhesion and solubility. The resin is odorless, features great water resistance and low water absorption. It is widely used as adhesives for magnetic tapes and magnetic cards, coating agents for beverage cans and waterproof tapes, as well as all kinds of coatings, inks and binders. 3.
