PANGAO MLC-10-80 Binary VC-VAc Copolymer Resin, High K-Value, for Anti-Corrosion Coatings, Plastic Primers

Full Name & Product Positioning

Full Name: PANGAO MLC-10-80 Binary Vinyl Chloride-Vinyl Acetate Copolymer Resin

High K-value binary VC-VAc copolymer industrial resin, approximately 90% vinyl chloride and only 10% vinyl acetate. With the highest K-value and viscosity number in this series, it shows good solubility in ketones, moderate solubility in ethyl acetate, and relatively weak solubility in aromatics. The film exhibits water and alcohol resistance characteristics. Suitable for anti-corrosion coatings, plastic primers, and related solvent-based formulations.

Core Advantages

1. High vinyl chloride content results in corresponding water and alcohol resistance in the film.

2. Shows good solubility in ketones, moderate solubility in ethyl acetate, and relatively weak solubility in aromatic solvents.

3. High K-value and viscosity number result in relatively high system viscosity at equivalent solids.

4. Suitable for anti-corrosion and solvent-resistant primer systems, providing adhesion improvement for various substrates.

5. Stable powder state, suitable for solvent-based anti-corrosion coating and plastic primer processing.

Main Application Areas

Core Applications: Anti-corrosion coatings, plastic primers, alcohol-resistant coating systems

Suitable Areas: Metal anti-corrosion primers, strippable coatings, specialty plastic paints, industrial protective coatings

Not Recommended: Pure water-based systems, food contact products, aromatics-based low ester-ketone formulations, high-flexibility soft film formulations.
