Quality Control

Our Dimer Acid Diglycidyl Ester is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistency in key parameters such as epoxy equivalent weight (EEW), viscosity, and acid value. Certificates of Analysis (COA) documenting these specifications 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). This product is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
