Quality Control

Our production of this polyester resin adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Key parameters such as acid value, viscosity, gel time, and color are rigorously monitored against internal specifications. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with each shipment. We support compliance with relevant global regulatory frameworks, including REACH, and can tailor grades to meet specific customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. For long-term storage, consider under an inert atmosphere to prevent oxidation and moisture absorption, which can affect resin properties.
