PANGAO VMC Carboxyl-Modified Ternary VC-VAc Resin, Equivalent to Dow VMCC, Medium Molecular Weight, for Air-Dry Topcoats, Marine Paints, Metal Coatings, Shoe Adhesive EVA Treatments
Full Name & Product Positioning
Full Name: PANGAO VMC Carboxyl-Modified Vinyl Chloride-Vinyl Acetate-Maleic Acid Terpolymer Resin
Medium molecular weight carboxyl-modified ternary VC-VAc copolymer industrial resin, approximately 83% vinyl chloride, 16% vinyl acetate, and 1% maleic acid, trichloroethylene-free. The molecular chain contains carboxyl functional groups, providing corresponding balance of chemical resistance, solubility, transparency, film strength, and thermoplasticity, with prominent interlayer adhesion characteristics. Suitable for air-dry topcoats, maintenance paints, marine paints, metal coatings, interlayer adhesion coatings, shoe adhesive EVA treatments, UV treatments, shoe adhesives, aluminum foil varnishes, hot-stamping back adhesives, inks, and related solvent-based formulations.
