Abstract
The disclosure involves a coated glazing, a method of manufacturing the glazing and the use of a layer based on silica and/or an organo silica deposited on a glazing to achieve a coefficient of kinetic friction between an exterior surface of the layer based on silica and/or an organo silica and a contact surface wiping device that does not substantially change between a dry state and a wet state of the surfaces. Also disclosed is a glazing suitable for combination with a wiping device, the combination of said glazing with a wiping device and the use of the glazing to facilitate a reciprocating motion of a part of a wiping device and/or to facilitate a tilting and/or flipping of a part of a wiping device.
Claims31
A coated glazing comprising:
- a transparent substrate directly or indirectly coated on a major surface thereof with at least one layer based on silica and/or an organo silica,
- wherein the at least one layer based on silica and/or an organo silica has a thickness of at least 5 nm but at most 45 nm, and
- wherein the at least one layer based on silica and/or an organo silica is obtained by partially or completely converting at least one layer based on one or more silazane.
A method of manufacturing a coated glazing comprising:
- depositing at least one layer based on one or more silazane on a major surface of a transparent substrate,
- partially or completely converting the at least one layer based on one or more silazane to at least one layer based on silica and/or an organo silica, and
- wherein the at least one layer based on silica and/or an organo silica has a thickness of at least 5 nm but at most 45 nm.
(canceled)
A glazing suitable for combination with a wiping means, comprising:
- a transparent substrate having a major surface,
- wherein, when combined with said wiping means, said major surface contacts said wiping means,
- wherein, in use, said wiping means wipes a first area of said major surface as a result of a part of said wiping means moving between a first position and a second position in a reciprocating motion,
- wherein, when said part of said wiping means is in the first position and/or when said part of said wiping means is in the second position, said part contacts a second area of said major surface, and
- wherein the coefficient of kinetic friction between a contact surface of said part of said wiping means and said major surface located in at least part of said second area of said major surface is higher than the coefficient of kinetic friction between a contact surface of said part of said wiping means and said major surface located in at least part of said first area that does not occupy the same area as said at least part of said second area.
The glazing according to claim 30, wherein said further layer based on silica and/or an organo silica is obtained by deposition using a precursor based on one or more of silane, tertraethyl orthosilicate (TEOS), and/or hexamethyldisiloxane (HMDSO).
