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 specific lot specifications are available upon request, supporting compliance with relevant industry standards for coatings and polymer materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent moisture absorption, which can affect product properties. Keep away from heat sources and open flame.
