Abstract:
A process for coating phosphated metal substrates with one or more organic coatings, in which after phosphating and before application of a first organic coating, the phosphated metal substrates are treated with an aqueous solution which contains 5 to 10000 ppm of dissolved titanium, vanadium, molybdenum, silver, tin, antimony and/or one or more elements of atomic numbers 57 to 83 in the form of inorganic and/or organic compounds, wherein the phosphated metal substrates are additionally connected as a cathode during the entire treatment or for part of the duration of the treatment.
