Quality Control

Our 1,1 (Hexamethylene)Diurea is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, moisture content, and impurity profiles to guarantee consistency and reliability for your industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product quality and handling properties. Keep away from incompatible materials such as strong acids and strong oxidizing agents.
