Quality Control

Our polymer products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with stringent industry specifications. Key parameters monitored include viscosity, hydroxyl value, isocyanate content, and thermal properties. Certificates of Analysis (COA) detailing all test results are available upon request. Our manufacturing processes adhere to ISO 9001 quality management principles, ensuring reliable supply and product performance.

Storage

Preserve in a tightly closed, moisture-proof 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 heat, open flames, and sources of ignition. Due to its reactive nature, isolate from strong acids, bases, and moisture to prevent premature curing or degradation.
