Quality Control

Our Poly(Oxy-1,2-Ethanediyl), .Alpha.-Hydro-.Omega.-Hydroxy-, Ether With Oxybispropanediol (4:1) is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as hydroxyl value, moisture content, and viscosity are available upon request to 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 a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert gas blanket to minimize potential oxidation.
