MULTILAYER LACQUERING PROCESS

摘要

A process for multi-coat painting in which a first coating of an electrophoretically separable aqueous coating (I) is electrophoretically applied to an electrically conductive substrate and then baked, whereupon further coatings are applied, where the coating agent (I) is such as to provide an electrically conductive coating when baked, whereupon, after the first coating has been baked an electrically insulating second coating of an electrophoretically separable aqueous coating agent (II) differing from (I) is electrophoretically separated and baked, whereupon as a third coating a basic paint coat of a coloured and/or effect-producing coating is applied and covered with a fourth transparent coat of a clear lacquer coating agent and baked together therewith, whereupon one or more further transparent topcoats are applied, in which the total dry coating thickness of the paint system is 90 to 130 .mu.m and the dry coating thickness of the transparent topcoat or coats is 40 to 80 .mu.m.
