The paintable phosphating film is porous, uniform and fine, and the paint penetrates into the pores to increase the adhesion of the coating. At the same time, the modified low-zinc film can resist the corrosion during the electrophoresis process of electrophoretic paint and enhance the electrophoresis effect. These are all beneficial to improving the corrosion resistance of the phosphating film + organic coating of the coating product. The corrosion resistance of the steel surface after phosphating is 2 times higher than that of direct coating without phosphating. The effects of phosphate coating on coating are as follows.
