Quality Control

Our o-Bis(2,3-Epoxypropoxy)Benzene is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for epoxy equivalent weight (EEW), purity, viscosity, and hydrolyzable chloride content. Certificates of Analysis (COA) documenting these 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 a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
