Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and molecular weight distribution are rigorously monitored using advanced analytical techniques including GPC, FTIR, and titration. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications 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). Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep containers tightly sealed when not in use to prevent moisture absorption and contamination. Store away from incompatible materials such as strong acids, bases, and oxidizing agents.
