Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as hydroxyl value, viscosity, isocyanate content, and moisture are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are available for every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F). Ensure containers are kept sealed when not in use to prevent moisture absorption and potential quality degradation. Store away from heat sources and incompatible materials such as strong acids, bases, and oxidizing agents.
