As an accredited Silicon-Aluminum Powder [Uncoated] factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | 25 kg net weight packaged in sealed, high-strength polyethylene-lined steel drums, labeled “Silicon-Aluminum Powder [Uncoated],” moisture-resistant, tamper-evident closure. |
| Shipping | Silicon-Aluminum Powder [Uncoated] should be shipped in tightly sealed, corrosion-resistant containers to prevent moisture and air exposure. Label as hazardous, following local and international transport regulations. Store away from oxidizers, acids, and sources of ignition. Handle with grounded equipment to avoid static discharge during transit. Use appropriate cushioning to prevent packaging damage. |
| Storage | Silicon-Aluminum Powder [Uncoated] should be stored in a cool, dry, well-ventilated area, away from moisture, acids, oxidizers, and sources of ignition. Keep the container tightly sealed and protected from physical damage. Use only non-sparking tools when handling. Store under inert atmosphere if possible to prevent oxidation, and clearly label all containers to avoid accidental mixing with incompatible materials. |
