As an accredited Solvent Red 218 factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Solvent Red 218 is typically packaged in a 25 kg net weight fiber drum with an inner plastic lining, labeled with product details. |
| Shipping | Solvent Red 218 is typically shipped in sealed, high-density polyethylene (HDPE) drums or containers to prevent moisture ingress and contamination. Each container is clearly labeled with hazard information per GHS/UN regulations. The material is transported as a non-dangerous good under normal conditions, but care is taken to avoid extreme temperatures and direct sunlight. |
| Storage | Solvent Red 218 should be stored in a tightly closed container in a cool, dry, and well-ventilated area away from sources of ignition and strong oxidizing agents. Avoid exposure to direct sunlight and moisture. Ensure that storage facilities are equipped with appropriate spill containment and fire suppression systems. Clearly label containers and restrict access to authorized personnel trained in chemical handling. |
