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 industry standards, including those for coatings and polymers. For specific grade requirements or regulatory support (e.g., REACH, FDA indirect food contact), please contact our technical team.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect processing and final product properties.
