Abstract
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.
