A high molecular weight resin containing approximately 86 percent vinyl chloride, 13 percent vinyl acetate, and 1 percent maleic anhydride. Because of the carboxyl functional group, VAM has excellent adhesion on metal, especially on aluminum foil, the resin foil also has a good adhesion on PVC , ABS, paper, textiles, beton, etc. At the same time, VAM has good water resistance, excellent oil, ester, acid, alkali and salt water solution resistance.
VAM is used for maintenance, marine, aluminum foil varnish, cans sealed paint, shoe adhesive, floor paint , silk screen printing and transfer ink, and is often used to make heat-sealable packaging coatings. It also can be used to produce the VC heat sealing plastic package for medical, Electro-chemical aluminum paint, thermal transfer adhesive.
