Quality Control

Our production of this aliphatic polyurethane resin adheres to stringent quality management systems, ensuring batch-to-batch consistency for critical coating applications. Key parameters such as viscosity, solids content, hydroxyl value, and color are rigorously tested against internal specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is 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, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources and open flame. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and skin formation.
