Quality Control

Our production of this polyurethane polymer adheres to strict batch-to-batch consistency protocols. Quality is monitored through key parameters including isocyanate (NCO) content, viscosity, hydroxyl value, and acid number to ensure predictable performance in downstream formulations. Certificates of Analysis (COA) detailing these specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to prevent moisture absorption and potential reaction. Store away from heat, sparks, and open flame.
