Quality Control

Our 2,2,4-Trimethylhexa-1,6-Diyl Diisocyanate is produced and handled under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, isocyanate content, and impurity profiles. Certificates of Analysis (COA) documenting these results are provided as standard, ensuring traceability and batch-to-batch consistency for our industrial partners.

Storage

Preserve in a tightly closed container, protected from light. Store under a dry, inert atmosphere (e.g., nitrogen) in a cool, well-ventilated area. Due to its high volatility and sensitivity to moisture, the container must be kept tightly sealed when not in use. Recommended storage temperature is 2-8°C to maintain optimal stability and prevent polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and water.
