The invention relates to self-cleaning paint coatings that exhibit the Lotus effect® and to an agent and a method for producing the same. The inventive paint coatings comprise a paint base coat and a top coat, which has structure-forming particles with an average particle diameter of <100 nm; said top coat is at least partially hydrophobic and has elevations interspaced at a distance of >50 nm. The agent contains a liquid medium, at least one hydrophobing agent that has been dissolved therein and the aforementioned structure-forming particles held in suspension. The method comprises the following steps: coating of a substrate with a paint coat, application of the liquid to pasty agent that forms the top coat to the partially cured or uncured paint base coat and curing of the top coat and if required, the paint base coat. |
