As an accredited Aromatic Polyisocyanate Crosslinkers factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Aromatic Polyisocyanate Crosslinkers are supplied in 25 kg tightly-sealed metal drums with hazard labeling and moisture-resistant inner lining. |
| Container Loading (20′ FCL) | A 20′ FCL of Aromatic Polyisocyanate Crosslinkers typically holds 16-18 metric tons, packed in steel drums or IBC tanks. |
| Shipping | Aromatic Polyisocyanate Crosslinkers should be shipped in tightly sealed, approved containers, clearly labeled as hazardous. Store and transport in cool, dry conditions, away from moisture, heat, and incompatible substances. Follow all relevant regulations for hazardous chemicals, using appropriate safety measures including proper documentation, protective gear, and spill containment procedures during transit. |
| Storage | Aromatic Polyisocyanate Crosslinkers should be stored in tightly sealed containers, in a cool, dry, well-ventilated area away from moisture, direct sunlight, heat, and incompatible materials like amines and alcohols. Keep away from ignition sources and ensure proper labeling. Storage temperature should typically be below 30°C to prevent degradation. Personal protective equipment should be used when handling these chemicals. |
| Shelf Life | Aromatic polyisocyanate crosslinkers typically have a shelf life of 6-12 months when stored in tightly sealed containers at 5–30°C. |
