The present invention relates to a hydrophobic coating for glass, ceramic, glass-ceramic substrates, the coating comprising two layers; One priming layer is applied directly on the substrate and comprises Si—R 3 —Si, wherein R 3 is selected from the group consisting of linear, branched or aromatic alkyl chains, preferably linear, wherein two The number of carbon atoms binding to the silicon atoms is less than 6 and is preferably between 1 and 4; The coating layer is bound to the priming layer and includes an alkylsilane at the hydrophobic / oleophilic perfluorinated end. The present invention also provides a method for obtaining such a coating on the substrate, as well as obtaining the substrate itself, of the monolithic, laminated or multiple glazing type, wherein the coating is provided on at least one part of the surfaces thereof. It is about. |
