Quality Control

Our production of this specialty polyurethane prepolymer adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, hydroxyl value, and residual monomer levels are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all 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 a recommended temperature of 15-25°C. This product is hygroscopic (moisture-sensitive) and must be protected from atmospheric moisture to prevent premature reaction and viscosity increase. Keep away from heat sources and incompatible materials such as strong bases, acids, and oxidizing agents.
