<p>The invention is used in the field of chemistry and relates to coatings which can be used, for example, for the production of paint films, and a method for production thereof. The object of the invention is to describe permanent coatings with hydrophobic to ultrahydrophobic properties. The object is attained by hydrophobic permanent coatings of a crosslinked layer of a hardener component (A) and resin component (B), whereby (A) and/or (B) comprise chemically coupled lateral and/or terminal perfluoroalkyl groups with at least one trifluoromethyl end group, with a coupling between the layer and the surface region of the substrate. The object is further attained with a method in which the coating agent containing perfluoroalkyl groups is applied to a surface in the form of a melt, powder, dispersion or solution, with input of energy a film formation is carried out in one or more stages with or without a partial cross-linking and at least one partial coupling and subsequently again with input of energy a complete cross-linking of the layer is carried out.</p> |
