Abstract
A method for coating metallic surfaces of substrates with surfaces of aqueous (coating) compositions in the form of a dispersion and/or a suspension containing at least one stabilized binder and a gelling agent, the cations having been dissolved out of the metallic surface of the substrate in a pretreatment stage and/or during the contacting. The invention further relates to such a coating based on an ionogenic gel, in which the coating is formed by a process further described herein.
