Abstract

The invention relates to a method for producing self-cleaning surface coatings, whereby an inventive coating agent dispersion or solution is applied with a thin coat to the surface and is dried thereon. Said coating agent dispersion or solution is comprised of: a) a film-forming plastic provided in the form of an aqueous dispersion or of a solution in an organic solvent; b) a hydrophobic polymer provided in the form of a powder with an average grain size ranging from 10-50 νm, which is insoluble in the above-mentioned solvent; c) a sufficient quantity of water and/or of an organic solvent for producing a coating agent that is capable of being spread or sprayed; d) whereby the applied layer is so thin that the grains of the hydrophobic polymeric powder are interspaced by a distance of 5 to 100 νm, and e) whereby the quantity of the film-forming plastic is measured so that it forms a layer after the solvent evaporates whose thickness is equal to 30-60 % of the average grain size of the hydrophobic powder.
