Quality Control

Our Bisphenol A-2,2-Bis-(Hydroxymethyl)-Propionic Acid-Epichlorohydrin Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of epoxy equivalent weight (EEW), viscosity, and purity. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from sources of heat, sparks, and open flame. As with many epoxy intermediates, prolonged exposure to moisture or elevated temperatures should be avoided to maintain product integrity.
