Patent ID: 8092913

Claim:
A process for obtaining a hydrophobic/oleophobic coating on a substrate comprising a glass, ceramic or vitroceramic material, said process comprising: a) applying to said substrate a first priming layer obtained from a priming agent of formula: (X 1 ) 3-q (R 1 ) q Si—R 3 —Si(X 2 ) 3-q ,(R 2 ) q , in which Si is silicon; R 3 represents a CH 2 or (CH 2 ) 2 linear carbon-based chain; R 1 and R 2 each represent an alkyl group or a hydrogen atom; X 1 and X 2 are identical or different hydrolyzable groups; and q and q′ are equal to 0 or 1, and b) depositing onto said first layer a hydrophobic coating comprising at least one fluorinated alkylsilane.
