Quality Control

Our production of this polyurethane prepolymer adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, hydroxyl value, and moisture content are rigorously monitored. Certificates of Analysis (COA) detailing these specifications are provided with each shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored under a dry, inert atmosphere (e.g., nitrogen blanket) to prevent premature reaction and viscosity increase. Recommended storage temperature is between 15°C and 25°C in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as water, alcohols, amines, and strong bases.
