Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems. Each batch is characterized for critical parameters including isocyanate (NCO) content, viscosity, and residual monomer levels to ensure consistency and performance. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature reaction and gelation. Keep away from heat, sparks, and open flame.
