Quality Control

Our production of Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-(1-Oxo-2-Propenyl)Oxy-, Ether With 2,2-Bis(Hydroxymethyl)-1,3-Propanediol (4:1) adheres to a stringent quality management system. Every batch undergoes comprehensive analytical testing, including assay, impurity profiling, and functional group analysis, to ensure it meets precise specifications for applications in sensitive industries like coatings and adhesives. Certificates of Analysis (COA) documenting purity, viscosity, color, acid value, and water content are provided to guarantee traceability and performance consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize viscosity increase or premature polymerization. Keep away from heat, sparks, and open flame.
