Quality Control

Our copolyester resins are manufactured under strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) documenting full specifications are available for every shipment. Our production facilities adhere to ISO 9001 standards, and materials can be supplied to meet specific regulatory or customer-defined requirements.

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 flames. Under these conditions, the product is stable for a minimum of 24 months from the date of manufacture. Protect from moisture to prevent potential hydrolysis or clumping.
