Abstract

A process for the electrophoretic application of self-cleaning enamel systems free form aluminium on sheet steel by the two layered/single stoving process, comprising applying a base layer in a thickness of 80 to 120 mu m to a steel substrate, and then applying a top coat to said base coat, said top comprising an enamel suspension having a specific conductivity adjusted to a value below 2000 mu S.cm-1.
