Quality Control

Our production of this copolyester resin adheres to a strict quality management system to ensure batch-to-batch consistency and performance reliability. All materials undergo rigorous analytical testing, including determination of acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color. Certificates of Analysis (COA) documenting these key parameters are provided with every shipment. We operate in compliance with ISO 9001 standards, and our quality protocols are designed to meet the specifications required for coatings, adhesives, and other industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials such as strong oxidizing agents. Under these conditions, the product is stable for extended periods. For bulk storage, ensure containers are kept tightly sealed when not in use to prevent moisture absorption and contamination.
