Process for the production of coated substrates |
摘要 |
A process for the production of coated substrates comprising the successive steps of: a) applying a coating composition A' onto one side A'' of a metal sheet to form a coating layer A which is electrically insulating when cured and applying a coating composition B' onto the opposite side of the metal sheet to form coating layer B which is electrically conductive when cured, wherein each of the coating compositions A' and B' are applied by coil coating, b) curing the two coating layers A and B, c) removing and shaping sheet metal parts provided with the cured coating layer A on one side A'' and with the cured coating layer B on the other side B'', d) optionally, assembling the coated shaped sheet metal parts to form a construction with outwardly directed sides A'' and e) electrodepositing an electrodeposition (ED) coating layer onto the electrically conductive surfaces and curing of the ED coating layer.
