Quality Control

Our production of this advanced polymer adheres to rigorous quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as viscosity, solids content, acid value, and epoxy equivalent weight are monitored using standardized analytical methods including titration, gel permeation chromatography (GPC), and infrared spectroscopy (IR). A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each 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 temperatures between 15°C and 25°C (59°F and 77°F). Keep away from sources of heat, sparks, and open flame. Due to its chemical nature, this product should be stored separately from strong acids, strong bases, and oxidizing agents. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption or solvent evaporation, which may alter product properties.
