HYDROPHOBIC COATING COMPRISING A PRIMING INCLUDING A BIS-SILANE AND A HYDROPHOBIC LAYER INCLUDING A FLUORINATED ALKYSILANE

The invention relates to a hydrophobic coating for a glass, ceramic or vitroceramic substrate, characterized in that it comprises two layers: a priming layer directly applied onto said substrate and comprising groups Si-R3-Si, R3 being chosen from the group constituted by linear, branched or aromati...

Beschreibung
Zusammenfassung:	The invention relates to a hydrophobic coating for a glass, ceramic or vitroceramic substrate, characterized in that it comprises two layers: a priming layer directly applied onto said substrate and comprising groups Si-R3-Si, R3 being chosen from the group constituted by linear, branched or aromatic, preferably linear, alkyl chains in which the number of carbons establishing the bond between the two silicon atoms is less than 6 and is preferably between 1 and 4, a coating layer in connection with said priming layer and comprising an alkylsilane with a hydrophobic/oleophobic perfluorinated end group. The invention also relates to a process for obtaining such a coating on a substrate as described previously, and also to the substrate itself, of the monolithic, laminated or multiple glazing type, equipped on at least part of at least one of its surfaces with said coating.
