Metal surface phosphating treatment: As a key raw material for manganese-based phosphating solution, it generates a dense manganese-based phosphate film. This significantly improves corrosion resistance, wear resistance, and paint film adhesion.
Widely used in black phosphating processes for: Automotive gears, fasteners, bearings, mechanical components, etc.
High-end ceramic glazes, electronic grade manganese salt precursors, alloy additives, etc.
📦 Packaging: Woven bags lined with polyethylene plastic bags, net weight 25kg/bag. Double-layer moisture-proof sealed packaging available.
🌡️ Storage: Store in a cool, ventilated, dry warehouse. Keep away from moisture, light, and oxidation. Avoid acidic materials and dust.
🚚 Transportation: Protect from rain and direct sunlight. Handle with care. Keep dry, as moisture directly affects phosphating performance.
🔥 Fire Control: Use water, sand, or fire extinguishers for fire fighting.
