CAS No.: 9003-22-9
Appearance: White powder
Packing: Paper-plastic compound bag, net weight 25 kg/bag.
VYHH is a high-molecular-weight vinyl chloride and vinyl acetate copolymer resin supplied for solvent-based coatings, printing inks and surface-treatment systems. The published molecular weight is approximately 27,000, with a vinyl chloride/vinyl acetate composition of 87±1%/13±1%.
The grade combines chemical resistance, solubility, coating strength and thermoplastic properties. It is intended for formulations using a sufficiently strong solvent blend; the current product data gives a 50% ketone and 50% aromatic-hydrocarbon blend as an example.
Solvent choice, resin concentration and compatibility should be checked in the customer's complete formulation before production.

The Specification table reproduces the items and values published on the current Hanghui product page. Refer to the sales contract and batch COA for shipment acceptance.
VYHH requires a solvent or thinner system with sufficient solvency. The current product information gives a blend of 50% ketone and 50% aromatic hydrocarbon as one example.
Prepare a small laboratory solution first and check clarity, viscosity, storage stability and compatibility with the other binders and additives. The stated MEK/EA result is a specification test and should not be treated as a universal production formula.
• Paper-plastic compound bag, net weight 25 kg/bag.
• Keep the bags closed and protect them from moisture, rain and packaging damage during handling and transport.
• Specific shelf life and storage-temperature limits are not stated on the current product page; confirm these against the latest TDS or sales contract before use.
Current TDS, SDS, batch COA and sample information are available upon request. Please state the application, required quantity and destination port when contacting our sales team.
