Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers contain a carboxyl function group ,so it provides excellent adhesion on metal,especially on aluminum foil. resin film also has a good adhesion on PVC, paper, textile. Because this copolymer also contain vinyl acetate function group, so it also has excellent acid,alkali and sale water resistance.menawhile it has oil and ester solution resistance. This copolymer offers a desirable balance of chemical resistance, solubility, diaphaneity, film strength, and thermoplasticity and it can be mixed and mutual soluble with other resin like alkyd resin, Epoxy resin Product Specification: item: value Test Standand Appearance: White Powder By visual Composition: Vinyl Acetates Content by mass 13�±1% Vinyl chloride Content by mass 86�±1% maleic acid content by mass 1�±1% ISO1159-1978 K value: 44-46 GB/T3401-1999 viscosity 50-54 GB/T3401-1999 Molecular Weight: 27000 Volatile Contents including moisture: â?¤1% GB/T2914-1999 Apparent density: 0.5 GB20022-2005 Black and yellow spots: â?¤20 GB9348-88 solubility: transparent solution By visual
