Quality Control

Our production of this advanced polymer resin adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Quality is verified through a suite of analytical tests including viscosity, epoxy equivalent weight, isocyanate content, and gel time measurements. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every shipment to support your quality assurance processes.

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). Ensure containers are kept tightly sealed when not in use to prevent moisture absorption, which can affect product performance.
