Full Name & Product Positioning
Full Name: PANGAO MVAF-T5 Hydroxyl-Modified Vinyl Chloride-Vinyl Acetate-Hydroxyalkyl Acrylate Terpolymer Resin
Relatively high molecular weight hydroxyl-containing ternary VC-VAc copolymer industrial resin, approximately 82% vinyl chloride, 10% vinyl acetate, and about 8% hydroxyl functional groups. With relatively high K-value and viscosity number, the system viscosity is high at equivalent solids. The film shows improved hardness and chemical resistance characteristics. Suitable for abrasion-resistant coatings, industrial coatings, high-viscosity inks, and related solvent-based formulations.
