Quality Control

Our production of this blocked polyurethane prepolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as blocked isocyanate content (NCO%), viscosity, color, and deblocking temperature are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment 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 temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent contact with atmospheric moisture, which can lead to premature reaction and gelation. Keep away from heat, sparks, and open flame.
