A high-throwing of the metal coating pre-treatment agent of zirconium

The present invention discloses a high throwing of the metal zirconium coating pre-treatment agent, the metal zirconium pretreatment agent zirconia nano / nano zirconium fluoride, water-soluble electroconductive polymer polythiophene or polypyrrole and ionic liquid etc. the metal zirconium pretreatment agent can slow the metal surface and the oxidation rate of corrosion damage is UV radiation, effect as conventional phosphating agent is quite effective, while the metal zirconium pretreatment agent easy to use, without environmental pollution, environmental protection.
