Quality Control

Our production of this advanced polymeric resin adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Key parameters such as viscosity, epoxy equivalent weight (EEW), isocyanate content, and gel time are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is 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 room temperature (15-25°C). 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.
