Quality Control

Our production of this polyester resin adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which can affect product properties.
