Quality Control

Our Epoxy Resin is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of epoxy equivalent weight (EEW), viscosity, and color. Certificates of Analysis (COA) documenting all key parameters 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). Keep away from heat sources and open flame. Moisture-sensitive; ensure containers are sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
