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 |
20080215026 | Superabsorbing Foam, Method for the Production and Use Thereof - A superabsorbent foam comprising from 0.01% by weight to 10% by weight of fibers composed of woodpulp or waste paper, based on the dry weight of the foam. | 09-04-2008 |
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 |
