This product is formulated with environmentally friendly organic acids as the primary oxidizing agent, supplemented with efficient anode-adsorbing intermediate additives, high-quality corrosion inhibitors, and a small amount of polymer passivation accelerators. It contains no acid-etching components, is non-toxic, and odorless. Through passivation with this product, it effectively ensures that the original color of the workpiece is not compromised, dimensions remain unchanged, and significantly enhances the salt spray resistance of stainless steel workpieces.
