Cold Water Soluble PVA 1788 for Construction Glue and Putty
HOPEWAY PVA 1788 is a partially hydrolyzed polyvinyl alcohol with degree of hydrolysis 87-89% and polymerization degree approx. 1700. It is cold water soluble, making it ideal for interior wall putty, construction glue, and dry mortar additives. With low ash and low sodium acetate content, it helps prevent efflorescence and ensures consistent mortar strength.
Key Selling Points
- Cold Water Soluble: Dissolves quickly in cold water without agglomeration, improving production efficiency in putty and glue manufacturing.
- Excellent Film-Forming: Enhances adhesion and crack resistance of wall putty, reducing powder falling and delamination.
- Low Ash Content: Minimizes wall efflorescence and maintains mortar compressive strength, meeting global indoor building standards.
- Stable Viscosity: With viscosity 20.5-28 mPa·s, ensures consistent batch-to-batch quality even in high humidity conditions.
- Non-Toxic: Water-soluble polymer that is safe for interior applications.
