Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, hydroxyl value, isocyanate content, and acid number are rigorously monitored. Certificates of Analysis (COA) documenting all relevant specifications are provided with each 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 a recommended temperature of 15-25°C. Keep away from heat, sparks, and open flame. This material is moisture-sensitive; ensure containers are sealed after use to prevent absorption of atmospheric moisture.
