A heat-settable composition for a coating which is hydrophobic, oleophobic and resistant to abrasion, wherein the coating contains a hydrolyzate obtained from a solution of:one or more epoxidized alkoxysilane having alkoxy groups which are directly linked to the silicon atom;a hydrolyzable, non-epoxidized silane;colloidal silica;a catalyst which promotes cleavage of an epoxy bond; andat least one fluorinated hydrolyzable alkylsilane; and the use of the heat-settable composition in the preparation of a coated substrate of organic glass or mineral glass material, coated with a coating obtained from the heat-settable composition, with the substrate preferably being a pane (comprised of glass or a polymeric material) or an ophthalmic lens. |
