Title: CORROSION PROTECTION
Abstract:
The invention relates to a coating material for producing a corrosion-resistant coating on an oxidized and/or hydroxylated metal surface, comprising the following: - at least one binder, - at least one particulate metal which comprises oxide- and/or hydroxyl groups, and - at least one platelet-shaped non-metal particle which comprises oxide- and/or hydroxyl groups, wherein the binder is capable of forming a covalent bond with the surface and the oxide- and/or hydroxyl groups of the at least one particulate metal and the at least one platelet-shaped non-metal particle. The at least one particulate metal has a lower standard potential than the metal surface to be coated, and the at least one binder is selected from the group consisting of alkoxysilanes, siloxanes, alkyl titanate, titanate, alkyl zirconate, zirconate, and mixtures thereof.
