Quality Control

Our Diurethane Dimethacrylate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and color are available upon request. We adhere to cGMP principles where applicable to ensure batch-to-batch consistency and reliability for critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). This product is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) to maximize shelf life and maintain purity. Keep away from heat, sparks, and open flame.
