METHOD FOR MANUFACTURING PAINTED METAL SHEET

摘要

A method for manufacturing a painted metal sheet by successive paintings comprises the steps of (a) subjecting a metal sheet plated with zinc or zinc alloy to an electrophoretic treatment with a water-soluble resin series paint to provide an undercoating, then (b) painting the steel sheet having the electro-deposited paint coating with a water-soluble or solvent-soluble paint to provide a final coat, and then (c) baking and drying the undercoat and the final coat at the same time.
