摘要： The invention relates to a method for coating a metallic surface with an aqueous composition for pretreating before applying another coating or for treating said metallic surface. In addition to water, the composition contains: a) at least one hydrolyzable or at least partially hydrolyzed silane; b) at least one metal chelate; c) at least one organic film former, and; d) at least one long-chain alcohol that serves as a film forming aid. The unsoiled, scoured, cleaned and/or pretreated metallic surface is brought into contact with the aqueous composition and a film is formed on the metallic surface, is subsequently dried, compacted in part or completely by film formation and, if necessary, additionally hardened. The dried and, if necessary, additionally hardened film has a layer thickness ranging from 0.01 to 10 µm. The invention also relates to corresponding aqueous compositions.

摘要： A process is disclosed for coating fine particles, in which the feed mixture contains: at least one monomer and/or at least one oligomer selected from monomers and/or oligomers of aromatic compounds and/or unsaturated hydrocarbon compounds suitable for forming an electroconductive oligomer, polymer, copolymer, block copolymer or graft copolymer; at least one type of anions which (1) are and/or can be incorporated as doping ions into the structure of the conductive polymer; (2) can be discharged from said structure in the event of a potential fall of the conductive polymer (reduction); and (3) can have an anti-corrosive effect in the presence of a metallic surface; at least one type of particles; if necessary, at least one oxidising agent and water and/or at least another solvent. A coating is formed from the feed mixture on the particle surface, the feed mixture being converted by oxidation into a conductive polymer in the presence of at least one type of mobile anti-corrosive anions. Alternatively, the fine particles are coated with a product mixture that contains a conductive polymer.

摘要： A process is disclosed for coating metallic surfaces with an anti-corrosive composition that contains a conductive polymer and is a dispersion that contains the at least one conductive polymer mainly or entirely in particulate form, as well as a binder system. The conductive polymer is at least one polymer based on polyphenylene, polyfuran, polyimidazole, polyphenanthrene, polypyrrole, polythiophene and/or polythiophenylene charged with anti-corrosive mobile anions. Alternatively, the metallic surfaces can be first coated with a dispersion based on conductive polymers in particulate form, then coated with a composition which contains a binder system.

摘要： The invention relates to a method for protecting a metal surface by means of a coating based on a corrosion-inhibiting composition containing the following component(s): a) at least one type of deposit substance comprising (1) anions incorporated by an oxidation reaction and (2) releasing at least a part of said anions for a potential variation between a redox potential of the deposit substance and an undisturbed corrosion potential of a metal surface or when a comparably small potential variation is produced on a defect, wherein said anions can inhibit a partial anodic or/and cathodic corrosion reaction or/and act as an adherence initiator, said anions comprise, respectively, an ionic radius non-impairing the migration thereof, possibly b) at least one type of matrix substance, wherein said deposit substance(s) disposed in the undisturbed areas of the coating are at least partially oxidised or at least partially doped by the anions and at least one type of the deposit substance in the disturbed areas of the at least partially reduced coating or devoid at least partially of doping anions, the coating is adjusted by selecting the contained components and the contents thereof in such a way that it is possible to act at least partially and prematurely against the generation or the progression of a delamination before an intense delamination occurred. The variants of the deposit substance optionally have a relatively low cation transport rate.
