Quality Control

Our cis-1,4-Cyclohexylene Diisocyanate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay by titration and isomer content determination by GC or HPLC, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures recommended for isocyanate handling (typically below 25°C). This material is hygroscopic (moisture-sensitive) and must be kept under a dry inert atmosphere (e.g., nitrogen) to prevent reaction with atmospheric moisture and CO2.
