    Abstract: Preparation, for obtaining corrosion protection layers to metallic surfaces, comprises at least one binding agent system (15-70 wt.%) that is hardened under atmospheric conditions, at least one corrosion preventing polymer agent (0.1-40 wt.%), at least one solvent (5-83.9 wt.%), and at least one component (1-70 wt.%) of fine-particle filler, pigment or dye. Preparation, for obtaining corrosion protection layers to metallic surfaces, comprises at least one binding agent system (15-70 wt.%) that is hardened under atmospheric conditions, at least one corrosion preventing polymer agent (0.1-40 wt.%), at least one solvent (5-83.9 wt.%), and at least one component (1-70 wt.%) of fine-particle filler, pigment or dye (where the corrosion preventing agent is obtained from the monomer building units of: (i) 70-30 mol.% of at least one monoethylenic unsaturated hydrocarbon and/or at least one monomer (with function groups X 1>) modified monoethylenic unsaturated hydrocarbons and vinyl ethers), (ii) 30-70 mol % of at least a 4-8C monoethylenic unsaturated dicarbonic acid and/or its anhydride or derivatives such as esters of the dicarbonic acids with alcohol of formula (OH-R 1>-X 2> n), amide and/or imide with ammonia and/or amine of formula (HR 2>N-R 1>-X 2> n), and (iii) 0-10 mol % of ethylenic unsaturated monomers (different from (i) and (ii), but copolymer of (i) and (ii)), where the quantities are related to the total quantity of all monomer containing copolymer). R 1>(n+1) valued group of 1-40C hydrocarbons, (where the non-adjoining C is replaced by O and/or N); R 2>H, 1-10C hydrocarbon group or -R 1>-X 2> n; n : 1-3; and X 2>functional group. Independent claims are included for: (1) a method for the corrosion protection by obtaining at least one corrosion protection layer with a thickness of at least 15 mu m, comprising applying the preparation on the polished or pre-coated metallic surface under atmospheric conditions, and hardening the applied layer under atmospheric conditions; and (2) a coated metallic surface obtained by the method.

    Abstract: The present invention relates to a composition for coating metallic surfaces, comprising a binder component; a corrosion inhibitor polymer based on an ethylenically monocarboxylic and dicarboxylic acid and, if appropriate, further ethylenical monomers, a solvent component, and, if appropriate, crosslinkable components, and also pigment/filler components. The invention further relates to processes for its preparation and also to methods of coating a metallic surface using the composition, to coated metallic surfaces thus obtained, and to the use of the composition as a primer, particularly in coil coating or in atmospheric corrosion control. After drying, the applied layer preferably has a thickness of at least 3.1 μm and is therefore thicker than a typical pretreatment layer.
