Quality Control

Our copolyester resin is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color to ensure consistent performance and batch-to-batch uniformity. Certificates of Analysis (COA) detailing all test results are available upon request.

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. Under these conditions, the product is stable for at least 24 months from the date of manufacture.
