Abstract

A process is disclosed for the production of metal sheets enamelled with two layers, wherein the sheet is coated, before shaping, with a polymer suspension. The sheet is then dried and shaped, and optionally is coated with an enamel frit. The sheet is then fired at a temperature of 560 to 850 degrees C. The binder in the polymer suspension is preferably a material which burns completely at melting and stoving temperature.
