20110045178	METHOD FOR THE ADJUSTMENT OF DEFINED MORPHOLOGIES OF SEGREGATED PHASES IN THIN LAYERS - A method of establishing defined morphologies of separated phases in thin coats, in which anisotropic particles (T) whose average particle diameter (D) is <1 μm and whose D/d ratio of the average particle diameter (D) to the average particle thickness (d) is >50 are introduced into the coating material used to produce said coats and comprises at least one polymer (P1), at least one polymer (P2) which is incompatible with the polymer (P1) in the solid phase and/or a crosslinking agent (V) which is incompatible with the polymer (P1) in the solid phase, where the polymers (P1) and/or (P2) have at least one functional group (a) which reacts during curing of the coating material to form covalent bonds. The disclosed coating material is applied to an uncoated substrate and/or to a precoated substrate and then cured and can be used in producing antistonechip OEM coat systems.	02-24-2011
20100323103	METHOD FOR THE PRODUCTION OF HIGH-IMPACT LAYERS - The invention relates to a method of increasing the stonechip resistance of OEM coat systems composed of an anticorrosion coat, a surfacer coat, and a concluding topcoat, in which 0.1% to 30% by weight, based on the nonvolatile fractions of the coating material, of electrically charged inorganic particles AT whose ratio D/d, the ratio of the average particle diameter (D) to the average particle thickness (d), is >50 and whose charge is at least partly compensated by singly charged organic counterions OG, are incorporated into the coating material that is used to produce at least one of said coats and that comprises at least one polymer P, and the coating material is applied and, lastly, is cured.	12-23-2010
