Quality Control

Our production of this advanced polymer adduct follows rigorous quality testing protocols to ensure batch-to-batch consistency and performance reliability. While specific grades can be tailored, our standard quality commitment includes verification of amine value, epoxy equivalent weight, viscosity, and color. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory 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). This product is hygroscopic (moisture-sensitive) and should be kept under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and potential degradation. Keep away from heat and incompatible materials.
