PANGAO MVAD Ternary Hydroxyl VC-VAc Resin, Equivalent to Nissin Solbin AL, Low Viscosity Fast-Drying Gravure Inks, Flexible Packaging Coatings

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.

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.
