Quality Control

Our production of this polymer adheres to rigorous quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO content, viscosity, and hydroxyl value are strictly monitored. A comprehensive Certificate of Analysis (COA) detailing specific specifications is provided with each shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from heat sources and open flame.
