摘要： A coil coating method for multilayer coating of a continuous metal strip, which is disposed in the strip passage, in which on a flat side of the metal strip, a curable polymer primer is applied by means of a roller application and cured in order to form an electrically insulating primer layer and a curable polymer varnish is applied onto said primer layer by means of roller application and cured in order to form an electrically insulating varnish layer, wherein at least one at least electrically conductive conductor track is printed on at least some areas between the primer layer and the varnish layer is proposed. In order to increase the reproducibility of the coil coating method, it is proposed that the conductor track be printed on some areas of the pre-cured primer layer and that the conductor track and varnish be applied using a wet-on-wet process.

摘要： A metal strip and a coil coating process for multilayer coating of an endless metal strip are disclosed in which a curable polymer primer is applied to a flat side of the metal strip with the aid of a roller application in order to form an electrically insulating primer layer, a curable polymer varnish is applied to this primer layer with the aid of a roller application and cured in order to form an electrically insulating varnish layer, and at least one electric conductor layer is printed at least in some areas between the primer layer and the varnish layer. In order to enable a stable and inexpensive electrical functionalization of a metal strip, it is proposed that an electrically polarizable layer be applied to at least some regions of the electric conductor layer and that the electric conductor layer and electrically polarizable layer be applied by means of a wet-on-wet process.
