Full Name & Product Positioning
Full Name: PANGAO MVAD Hydroxyl-Modified Vinyl Chloride-Vinyl Acetate-Vinyl Alcohol Terpolymer Resin
Low molecular weight hydroxyl-containing ternary VC-VAc copolymer industrial resin, approximately 90% vinyl chloride, 4% vinyl acetate, and about 6% vinyl alcohol. With relatively low K-value and viscosity number, the dissolved system has low viscosity. Suitable for low-viscosity fast-drying gravure inks, high-solids coatings, flexible packaging film coatings, and related solvent-based formulations.

• Vinyl Alcohol Content: ~6 wt%
• K-Value: 36-38
• Viscosity Number: 34-38
• Average Molecular Weight: ~22,000
• Solid Content: 100 wt%
• Volatile Matter: ≤0.5%
• Standard Packaging: 25kg paper-plastic composite bag, 1kg sample pack available
• Reference Equivalent: Nissin Chemical Solbin AL
Core Advantages
1. Relatively low molecular weight results in low solution viscosity at equivalent solids, suitable for high-solids formulation processing.
2. Soluble in ester solvents with transparent solutions, with relatively fast solvent release.
3. Provides pigment wetting and dispersing assistance, supporting color development in fast-drying ink systems.
4. Film exhibits certain flexibility characteristics, providing adhesion improvement for flexible packaging film substrates.
5. Stable powder state, suitable for high-speed printing ink formulations.
