Quality Control

Our production of this specialty polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for demanding industrial applications. Key parameters such as NCO content, viscosity, solids content, and color are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to guarantee compliance with your formulation requirements.

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). Keep away from strong bases and organic solvents. The container must be kept tightly sealed to prevent moisture absorption and contamination.
