Quality Control

Our production of this unsaturated polyester resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, and reactivity are rigorously tested. Certificates of Analysis (COA) documenting full specifications are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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 and bases. For long-term storage, consider under an inert atmosphere to prevent premature cross-linking.
