Quality Control

Our production of this polymeric resin adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as acid value, hydroxyl value, viscosity, and glass transition temperature (Tg) are monitored. Certificates of Analysis (COA) detailing these specifications are available for every shipment. While produced under ISO 9001 quality management principles, specific grades can be tailored to meet customer-defined specifications or relevant industry standards.

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, sparks, and open flame. As a polymeric material, it should be stored away from strong oxidizing agents. Ensure containers are kept sealed when not in use to prevent moisture absorption or contamination.
