Quality Control

Our production of this polyurethane prepolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as isocyanate (NCO) content, viscosity, 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 protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade (typically 15-25°C). This product is hygroscopic (moisture-sensitive). Prolonged exposure to atmospheric moisture will lead to premature reaction and product degradation.
