Quality Control

Our 1,2,3-Propanetriyltris[Oxy(1-Methyl-2,1-Ethanediyl)] Triacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, color, and functionality. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profiles, and physical properties is provided with each shipment to guarantee consistency and support your quality assurance protocols.

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). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and prevent polymerization. Keep away from heat, sparks, open flames, and strong oxidizing agents.
