A method for finishing or coating a metal substrate, in which the metal is first coated with a silane adhesion promoter as a thin film prior to application of a primer and/or basecoat or topcoat. The method, useful in the original manufacture of trucks, does not require sanding or baking to achieve adhesion of the coating to the substrate.
L'invention concerne un procédé pour appliquer une couche de finition sur un substrat métallique, dans lequel le métal reçoit d'abord un mince film de silane comme promoteur d'adhésion, avant l'application d'une couche d'apprêt et et/ou d'une couche de base ou d'une couche finale. Le procédé est utile dans l'industrie de fabrication de camions et il ne nécessite par un ponçage ou une cuisson pour assurer l'adhésion du revêtement sur le substrat.
