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

The invention concerns a hydrophobic coating for a glass, ceramic, glass-ceramic substrate, characterized in that it comprises two layers: one priming layer applied directly on said substrate and comprising Si-R3-Si, R3 being selected among the group consisting of linear, branched, or aromatic alkyl...

Beschreibung
Zusammenfassung:	The invention concerns a hydrophobic coating for a glass, ceramic, glass-ceramic substrate, characterized in that it comprises two layers: one priming layer applied directly on said substrate and comprising Si-R3-Si, R3 being selected among the group consisting of linear, branched, or aromatic alkyl chains, preferably linear, wherein the number of carbon atoms binding the two silicon atoms is less than 6 and preferably between 1 and 4; a coating layer bound to said priming layer and comprising an alkylsilane at a hydrophobic/oil-repellent perfluorinated terminal. The invention also concerns a method for obtaining such a coating on said substrate, as well as the substrate itself, of the monolithic, laminated or multiple glazing type, provided on at least one part of at least one of its surfaces with said coating. ® KIPO & WIPO 2008
