Quality Control

Our production of this copolyester resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, glass transition temperature (Tg), and melt viscosity are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We support compliance with relevant industry standards for coatings and polymers.

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 heat sources and open flame. As with many polymeric materials, prolonged exposure to high humidity should be avoided to prevent potential clumping or property changes.
