20080197020 | Method for Producing Painted, Flat Metallic Moulded Bodies - Flat shaped bodies which comprise at least one metallic layer, a conversion coat applied thereto, and at least one paint coat, and methods for producing such bodies starting from flat, metallic, semifinished products. | 08-21-2008 |
20080199714 | Method For the Passivation of Metal Surfaces With Compositions Comprising Polymers With Acid Groups and Waxes - Process for the passivation of metallic surfaces, in particular of strip metals, by treatment of the surface with an acidic, aqueous preparation which comprises at least one water-soluble acid group-containing polymer and at least one wax. | 08-21-2008 |
20080233390 | Polymer Composition For Corrosion Protection - 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. | 09-25-2008 |
