  • Process for obtaining a textured glass substrate coated with an antireflective coating of sol-gel type
    Patent number: 11465934
    Abstract: A process for obtaining a material including a textured glass substrate coated, on at least one of its textured faces, with an antireflective coating of sol-gel type based on porous silica, includes a stage of application, to the at least one textured face of the substrate, of a solution containing at least one silica precursor and at least one pore-forming agent, then a heat treatment stage targeted at consolidating the antireflective coating. Before the application stage, the glass substrate is subjected to a preheating stage, so that the at least one textured face intended to be coated with the antireflective coating has a temperature within a range extending from 30° C. to 100° C. immediately before the application stage.
