Abstract：The influence law of anti- fingerprint film with the change of coating pretreatment process for chromium- free anti- fingerprinting hot dip galvanized steel sheets was revealed by experiments under the limited condition of production technology. And the influence law of film mass on the application properties of the product was further studied, including their conductibility, wear resistance, fingerprint resistance, heat resistance, painting adhesiveness and corrosion resistance, which could be provided as related technology reference. The results showed that after coating pretreatment, the anti- fingerprint film would have certain mass loss, which was the decisive factor for final application properties of the product. So the film mass should be controlled in the range of 1.0～1.3g/m2 to obtain production of chromium- free anti- fingerprinting hot dip galvanized steel sheet with excellent combination properties.
