Quality Control

Every batch of this advanced polymer is manufactured under strict quality management systems to ensure consistency in performance-critical parameters like molecular weight distribution, functional group content, and viscosity. Our rigorous quality testing includes advanced analytical techniques to verify composition and purity. A comprehensive Certificate of Analysis (COA) detailing key specifications such as solids content, acid number, isocyanate content (NCO%), and solution viscosity is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place with low humidity. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Ensure the container is kept sealed when not in use to prevent moisture absorption and potential polymerization or property degradation.
