1. A method for bonding a substrate with at least one layer of silicone in order to obtain a composite, comprising:

  • a first phase of application, during which a first layer comprising at least one organosilane is applied to at least one first surface of the substrate;

    a second phase of application, during which a second layer comprising silicone is applied on the first layer, wherein the organosilane has, during the second phase of application, at least one silicon bonded with at least one hydroxy;

    a phase of surface treatment, which precedes the first phase of application and during which at least either the first or a second surface of the substrate is treated so that the first surface has an angle of contact greater than an angle of contact of the second surface, wherein during the first phase of application, the organosilane deposits selectively on the first surface with respect to the second surface.
