As an accredited Diisocyanate factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | The Diisocyanate is packaged in a sealed 200-liter steel drum with hazard labels, safety data sheet, and proper UN identification. |
| Shipping | Diisocyanate must be shipped in tightly sealed, approved containers, clearly labeled as hazardous. It requires transportation in compliance with regulations for toxic and reactive substances, avoiding heat and moisture. Appropriate hazard documentation and emergency response information should accompany the shipment. Personnel handling must wear protective equipment and follow all safety protocols. |
| Storage | Diisocyanates should be stored in tightly sealed containers, away from moisture, heat, and direct sunlight. They must be kept in a cool, well-ventilated area, separated from incompatible substances such as amines, alcohols, and acids. Proper labeling and secondary containment are essential to prevent leaks. Access should be restricted to trained personnel, and appropriate safety measures should be strictly followed. |
