| 摘要 |
The present invention relates to a method for at least single-sided application of a topcoat layer to a substrate, comprising, as step (a), at least partial coating of at least one metal surface of a substrate that has been at least partly coated with at least one primer layer with an aqueous coating composition comprising at least one polymer dissolved or dispersed therein, wherein the coating composition additionally contains at least one mixed hydroxide of the general formula (I) and the method is a coil-coating method, to a topcoat layer which has been applied to at least one side of the substrate and is obtainable by this method, to a substrate which has been coated at least partially and at least on one side with a topcoat layer by this method, and to use of this coating composition for at least partial coating of at least one metal surface of a substrate that has been at least partly coated with at least one primer layer with a topcoat layer in a coil-coating method. |
