Quality Control

Our production of this advanced prepolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, hydroxyl value, and residual monomer levels are rigorously monitored using analytical techniques including titration, GPC, and FTIR. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and regulatory compliance 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). Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
