As an accredited Anhydride Curing Agents factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Anhydride Curing Agents are packaged in 25 kg net weight polyethylene-lined steel drums, ensuring moisture protection and safe, leak-proof transport. |
| Container Loading (20′ FCL) | Container Loading (20′ FCL) for Anhydride Curing Agents: 16-18MT net weight, packed in 25kg bags/drums, securely palletized for export. |
| Shipping | Anhydride curing agents should be shipped in tightly sealed, corrosion-resistant containers. Store and transport in cool, dry, well-ventilated areas away from moisture, acids, and bases. Ensure containers are labeled according to hazardous material regulations. Follow all local, national, and international shipping guidelines for chemicals. Wear appropriate protective equipment during handling. |
| Storage | Anhydride curing agents should be stored in tightly sealed containers, away from moisture, acids, and alkalis, in a cool, dry, and well-ventilated area. Avoid direct sunlight and sources of ignition. Use corrosion-resistant storage materials and ensure that the storage location has proper spill containment. Clearly label containers and keep them inaccessible to unauthorized personnel to prevent accidents or contamination. |
| Shelf Life | Anhydride curing agents typically have a shelf life of 12–24 months, provided they are stored in sealed containers under cool, dry conditions. |
