| DX309 | Finishing Fluid | Rust Preventionfor Cold-RolledSteel Strips | Previously, rust preventive oil was used for interim rust protection between processes. This made subsequent surface treatment preparation cumbersome due to the need for thorough cleaning before surface treatment. By compounding DX309 into an alkaline finishing fluid, interim rust protection is achieved without complicating the subsequent cleaning process. Current process: pickling → water washing → finishing → air drying →drying → storage (requires temporary rust protection) → water washing → other surface treatments. |
