Chemical film-forming solution, dyeing method for metal zipper teeth, metal zipper teeth, and zippers.

Abstract

The invention proposes a chemical transformation film solution containing selenium dioxide and sodium persulfate, beneficial for creating highly corrosion-resistant colored coatings on the surface of metal sliding zipper teeth. The chemical transformation film solution for metal sliding zipper teeth contains SeO2, CuCl2, H2SO4, and Na2S2O8. A method for coloring metal sliding zipper teeth, colored coated metal sliding zipper teeth, and sliding zippers with rows of these metal sliding zipper teeth is also proposed.
