Quality Control

Our production of this blocked polyurethane prepolymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical formulation performance. Key parameters such as blocked isocyanate content, viscosity, solids content, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing specifications and test results. Our quality protocols are designed to support compliance with relevant industry standards for coatings and adhesives.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at a recommended temperature of 15-25°C (59-77°F). Due to its hygroscopic nature, prolonged exposure to atmospheric moisture must be avoided to prevent premature reaction and product degradation. Keep away from heat sources and open flame.
