Quality Control

Our production of this copolyester resin adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters like acid value, hydroxyl value, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) are provided with each shipment, detailing key specifications. We support compliance with relevant global regulatory frameworks, including REACH, and can tailor quality protocols to meet specific customer or industry standards.

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 strong heat sources, open flames, and incompatible materials such as strong bases and oxidizing agents. The product may be hygroscopic; ensure containers are sealed after use to prevent moisture absorption.
