Quality Control

Every batch of our blocked fluorinated polyisocyanate is manufactured and tested under a strict quality management system. We ensure product consistency and performance through rigorous analytical controls, including determination of blocked isocyanate content, viscosity, and fluorine content. A comprehensive Certificate of Analysis (COA) detailing purity, key physical properties, and performance indicators is provided with each shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept sealed under a dry atmosphere (e.g., nitrogen blanket) after opening to prevent premature reaction and maintain shelf life. Keep away from strong acids and organic solvents.
