As an accredited Toluene-2,4-Diisocyanate factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | A 250 mL amber glass bottle, tightly sealed, labeled "Toluene-2,4-Diisocyanate," with hazard warnings and manufacturer details prominently displayed. |
| Shipping | Toluene-2,4-Diisocyanate is shipped as a hazardous material under UN2078. It must be transported in tightly sealed, corrosion-resistant containers, protected from heat and moisture. Proper labeling, placarding, and documentation are required. During shipping, personal protective equipment and emergency procedures must be in place due to its toxic and reactive nature. |
| Storage | Toluene-2,4-Diisocyanate should be stored in a cool, dry, well-ventilated area away from moisture, heat, and direct sunlight. Keep the container tightly sealed and separate from incompatible substances, such as amines, alcohols, and strong acids or bases. Use corrosion-resistant containers, and ensure proper labeling and secondary containment to prevent leaks or spills. Store away from food and oxidizers. |
