Quality Control

Our production of this polyurethane polymer adheres to strict quality management systems, ensuring batch-to-batch consistency for critical performance parameters such as NCO content, viscosity, and acid value. Each lot is analyzed against stringent internal specifications to guarantee suitability for demanding industrial applications. A comprehensive Certificate of Analysis (COA) detailing key physicochemical properties is provided with every shipment.

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). Keep containers tightly sealed when not in use to prevent moisture absorption, which can affect reactivity and properties. Isolate from strong acids, bases, and oxidizing agents.
