Quality Control

Our production of this polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Quality is verified through parameters such as isocyanate (NCO) content, viscosity, hydroxyl value, and residual monomer levels. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment. We support compliance with REACH and other global regulatory frameworks as required.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (typically 15-25°C). Containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
