PVA 2488 High-Viscosity Grade for Construction Materials

PVA 2488 is a high-viscosity polyvinyl alcohol grade developed for demanding bonding and reinforcement applications. Featuring a viscosity of approximately 44–50 mPa·s and an alcoholysis degree of 87–89%, it delivers superior adhesive strength, enhanced film toughness, and excellent mechanical stability. This grade is commonly used in dry-mix mortar systems, gypsum-based building materials, and cement modification formulations where increased cohesion and crack resistance are required. In emulsion polymerization, PVA 2488 acts as a protective colloid for vinyl acetate-based systems, improving emulsion stability and particle distribution. Screen printing adhesives, specialty construction glues, and high-strength paper laminates also benefit from its strong binding capacity. Industrial users select PVA 2488 when structural integrity and durability outweigh flow considerations. For project-specific formulations or pricing guidance, professional consultation is advised to ensure performance targets are fully met.
