Quality Control

Our production of this polyester resin adheres to strict quality management systems. Each batch is characterized for critical parameters including acid value, hydroxyl value, viscosity, glass transition temperature (Tg), and color to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) detailing these specifications are provided and 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 strong acids and organic solvents. The material should be stored under dry conditions to prevent moisture absorption, which may affect properties.
