Quality Control

Our production of this advanced polymer adheres to strict quality management systems. Every batch undergoes comprehensive analysis to ensure consistency in critical parameters such as NCO content, viscosity, and equivalent weight. Certificates of Analysis (COA) detailing these specifications are provided with each shipment to guarantee reliable performance in your formulations.

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). This product is hygroscopic (moisture-sensitive); containers must be kept sealed under a dry atmosphere (e.g., under dry nitrogen) to prevent moisture absorption and premature reaction. Keep away from heat, sparks, and open flame.
