Quality Control

Our Diglycidyl Ether is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and verification of key physical properties. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). Due to its hygroscopic and highly volatile nature, the container must be kept tightly sealed when not in use to prevent moisture absorption and evaporation. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids, bases, and oxidizing agents.
