Quality Control

Every batch of [2-(2-Hydroxypropoxy)-1,3-Propanediyl]Bis[Oxy(1-Methyl-2,1-Ethanediyl)] Diacrylate is manufactured and tested under a strict quality management system. We ensure consistent high purity and performance through comprehensive analytical methods including HPLC, GC, and titration. A detailed Certificate of Analysis (COA) documenting assay, identity, color, acidity, and moisture content is provided with each shipment to guarantee compliance with your specifications.

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 light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). It is recommended to store under an inert gas blanket (e.g., nitrogen or argon) to maximize shelf life and prevent polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and bases.
