Quality Control

Our production of this unsaturated polyester resin adheres to strict quality management systems. Each batch is characterized for critical parameters including acid value, viscosity, and reactivity to ensure consistent performance in downstream formulations. Certificates of Analysis (COA) detailing batch-specific properties are available upon request, providing full traceability and compliance data for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, and open flame. To prevent premature cross-linking, avoid prolonged storage at elevated temperatures and ensure containers are sealed to minimize exposure to air.
