As an accredited Trimethylhexamethylene Diisocyanate factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The packaging for Trimethylhexamethylene Diisocyanate consists of a 25 kg steel drum, clearly labeled with hazard warnings and product details. |
| Shipping | Trimethylhexamethylene Diisocyanate must be shipped as a hazardous material in tightly sealed, corrosion-resistant containers. It should be transported under cool, dry conditions, away from moisture, heat, and incompatible substances. Appropriate hazard labeling, UN number 2489, and safety documentation are required to ensure regulatory compliance and safe handling during shipping. |
| Storage | Trimethylhexamethylene Diisocyanate should be stored in tightly sealed containers, in a cool, dry, and well-ventilated area away from moisture, heat sources, and direct sunlight. Keep away from incompatible substances such as acids, alcohols, amines, and strong bases. Storage areas should be clearly labeled and equipped with spill containment and suitable fire suppression systems due to the chemical’s reactivity and potential health hazards. |
