Quality Control

Our epoxy resin polymers are manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency in epoxy equivalent weight (EEW), viscosity, color, and hydrolyzable chloride content, which are critical for downstream processing and final product performance. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. We can support compliance with relevant industry standards, including those for electronics (UL) and composites.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Avoid exposure to moisture, heat, and incompatible materials such as strong acids, bases, and oxidizing agents. Under recommended conditions, the product is typically stable for 24 months from the date of manufacture.
