Quality Control

Our 1-Isocyanato-3-(Isocyanatomethyl)-1-Methylcyclohexane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay, isocyanate content, and impurity profile analysis, to ensure it meets exacting specifications for high-performance applications. A comprehensive Certificate of Analysis (COA) is provided with each shipment, detailing purity and key physical-chemical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture and CO2. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
