PANGAO FVAM Carboxyl-Modified Quaternary VC-VAc Resin, Ultra-High Molecular Weight, for PVC Panel Lamination Adhesives, Marine Paints, Metal Coatings, Aluminum Foil Varnishes
Full Name & Product Positioning
Full Name: PANGAO FVAM Carboxyl-Modified Vinyl Chloride-Vinyl Acetate-Maleic Acid-Maleic Anhydride Quaternary Copolymer Resin
Ultra-high molecular weight carboxyl-modified quaternary VC-VAc copolymer industrial resin, approximately 85% vinyl chloride, 13% vinyl acetate, 1% maleic acid, and 1% maleic anhydride. The molecular chain contains carboxyl functional groups, providing adhesion improvement for smooth substrates such as metal, especially aluminum foil. Suitable for PVC panel lamination adhesives, marine maintenance paints, metal coatings, aluminum foil varnishes, can seal coatings, shoe adhesives, floor coatings, cement coatings, heat-seal packaging coatings, and related solvent-based formulations.

Core Advantages
1. Molecular chain contains carboxyl functional groups, providing adhesion improvement for smooth substrates such as metal and aluminum foil.
2. Ultra-high molecular weight structure provides potential for improved film strength and chemical resistance.
3. Shows good solubility in ketone solvents with certain ester solubility, with transparent solutions.
4. Can be blended with LC-40 for heat-seal packaging coatings, providing adjustment for heat-seal temperature and strength.
5. Provides adhesion improvement for PVC, ABS, paper, textiles, concrete, and other substrates.
