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 Technical Parameters Appearance White free-flowing powder   Vinyl Chloride Conten ~85 wt% Vinyl Acetate Content ~13 wt%   Maleic Acid Content ~1 wt% Maleic Anhydride Content ~1 wt% Carboxyl Functional Group Content ~2 wt%   K-Value  ~46   Average Molecular Weight  ~27,000 Solid Content 100 wt% Volatile Matter ≤1% Standard Packaging 25kg paper-plastic composite bag 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. Main Application Areas Core Applications:  PVC panel lamination adhesives, marine maintenance paints, metal coatings, aluminum foil varnishes Suitable Areas:  Can seal coatings, shoe adhesives, floor coatings, cement coatings, heat-seal packaging coatings (blended with LC-40), VC seal plastic packaging coatings, electrochemical aluminum coatings, heat-transfer adhesives Not Recommended:  Pure water-based systems, food contact products, pure ester single-solvent low-solids formulations, high-flexibility soft film formulations.
