Abstract (en)

[origin: WO0163009A2] The invention concerns a method which consists in: providing a protective treatment against corrosion to the initial sheet metal using an aqueous emulsion containing colloids based on acrylic and/or methacrylic polymer; a step which consists in applying a coat of liquid enamelling composition comprising an enamel frit capable of being vitrified; a baking step adapted to vitrify said frit. The invention is characterised in that said method does not comprise a step for degreasing said surface subsequent to the protective treatment. The invention provides the advantages of improved adherence of the enamel and a simpler process.
