Abstract
A splash screen, and a process for making a splash screen, comprising a glass sheet, the glass sheet comprising, a substrate of soda lime silica glass having a coating deposited on at least at least a first surface, the coating comprising a corrosion-protection layer deposited directly on the first surface of the substrate, the corrosion-protection layer having a thickness in the range 24 nm to 125 nm and comprising pyrolytically deposited silica with intentional doping of 7 atom % or lower. The splash screen provides reduced moisture induced corrosion of the glass surface.
Claims28
A splash screen comprising a glass sheet, the glass sheet comprising:
- a substrate of soda lime silica glass having a coating deposited on at least a first surface,
- the coating comprising a corrosion-protection layer deposited directly on the first surface of the substrate, the corrosion-protection layer having a thickness in the range 24 nm to 125 nm and comprising pyrolytically deposited silica with intentional doping of 7 atom % or lower,
- further comprising a second corrosion-protection layer deposited on the second surface of the substrate, the second corrosion-protection layer comprising silica deposited from a liquid coating composition comprising a polysilazane;
- and
- wherein the splash screen is a bath screen and/or a shower screen and wherein the glass substrate with corrosion-protection layer passes standard EN1096.
A process for manufacturing a splash screen comprising a glass sheet, the process comprising:
- providing a substrate of soda lime silica glass, pyrolytically depositing a corrosion-protection layer directly on a first surface of the substrate, the corrosion-protection layer comprising silica with intentional doping of 7 atom % or lower and being deposited to a thickness in the range 24 nm to 125 nm,
- further providing a liquid coating composition comprising a polysilazane, contacting the second surface of the substrate with the coating composition, and
- curing the coating composition at a predetermined curing temperature thereby forming a further layer comprising silica on the second surface, and
- wherein the splash screen is a bath screen and/or a shower screen and wherein the glass substrate with corrosion-protection layer passes standard EN1096.
