Quality Control

Our copolyester resin is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each production lot undergoes comprehensive analysis, including tests for acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) detailing all specification parameters are available upon request to support your quality assurance protocols.

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 typically stable for 24 months from the date of manufacture. For long-term storage, consider using under an inert atmosphere to prevent oxidation.
