Quality Control

Every batch of our Poly(Oxy-1,2-Ethanediyl), .Alpha.,.Alpha.-1,6-Hexanediylbis.Omega.-(1-Oxo-2-Propenyl)Oxy- undergoes rigorous quality testing to ensure compliance with stringent industry standards. Our quality assurance protocol includes verification of critical parameters such as acrylate functionality, molecular weight distribution, and purity. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee batch-to-batch consistency and support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified for the specific grade. This compound is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to maximize shelf life and maintain product integrity.
