Quality Control

Our production of 1-Isocyanato-4-(Isocyanatomethyl)-1-Methylcyclohexane adheres to stringent quality management protocols. Every batch is analyzed to ensure high purity and consistency, with specifications meeting the demands of advanced polyurethane formulations. A comprehensive Certificate of Analysis (COA) detailing assay, isocyanate content, color, and impurity profiles is provided with each shipment to guarantee reliable performance in your applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
