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 color are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture which may affect product performance.
