Product Details

Carboxyl-Modified Vinyl Chloride/Vinyl Acetate Terpolymers

Grade VMA: It is white powder,ketone soluble with colorless,transparent solution, and because of the carboxyl functional group, it has excellent adhesion on metal, especially on aluminum foil, the resin foil also has a good adhesion on PVC, ABS, paper, textiles, beton, etc. Moreover, it offers a desirable balance of chemical resistance, solubility, diaphaneity, film strength, and thermoplasticity. And Ink Raw Material Vinyl Chloride Copolymer Resin has excellent interbedded adhesion.

Vinyl Acetate Application:

VMA grade yields the good balance of solubility and viscosity properties needed for high-build, air-dry maintenance finishes,and it is often used to make coatings and adhesives applications where higher solids are desirable. It can be used in air-dry finishes, such as maintenance,marine,and metal coatings, interbedded adhesive,aluminum foli varnish,UV surface treatment,UV primer,thermal transfer adhesive, shoe adhesive, ink-jet and metal inks,etc.
