Polyvinyl Alcohol PVA1788 Partially Hydrolyzed for Construction and Adhesives

HOPEWAY PVA1788 is a partially hydrolyzed (87-89%) polyvinyl alcohol with a degree of polymerization around 1700, offering excellent cold water solubility. This grade is specifically formulated for construction applications such as interior wall putty, repair mortar, and tile adhesive, providing strong adhesion, water resistance, and crack resistance.

Key Selling Points

• Cold Water Soluble: PVA1788 dissolves readily in cold water, simplifying mixing and reducing energy costs in putty production.
• Alkaline Cement Compatibility: With 87-89% hydrolysis, PVA1788 is specifically recommended for use in alkaline cement systems, ensuring stable performance.
• Low Ash & Low Impurities: Low ash and low sodium acetate content prevent wall efflorescence and maintain mortar compressive strength.
• Enhanced Adhesion & Water Resistance: Improves putty adhesion, water resistance, and crack resistance, reducing product delamination and powder falling.
• Proven in Brazil: A Brazilian construction chemical distributor has purchased 1120 tons annually for over 2 years, achieving over 60% reduction in product return rate.
