Quality Control

Our production of this polyester resin adheres to stringent quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including tests for acid value, viscosity, gel time, and thermal properties. Certificates of Analysis (COA) documenting all critical specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 sources, open flames, and incompatible materials such as strong oxidizers. For long-term storage, consider under an inert atmosphere to prevent moisture absorption and premature cross-linking.
