Abstract:

A coated article (e. g. , a coated glass article) is provided with a low-emissivity, water-sheeting coating. The coating comprises a sputtered silica layer over a pyrolytically-applied dielectric layer. In certain embodiments, an automobile windscreen is provided with a low-emissivity, water-sheeting coating. Also provided are methods of rendering a surface of a substrate (e. g. , a pane of glass) resistant to soiling and staining, such as by depositing on the substrate a low-emissivity, water-sheeting coating.

Abstract:

A glass article which has a water-sheeting coating. In one embodiment, a glass sheet is provided bearing a sputtered water-sheeting coating comprising silica on an exterior surface and bearing a reflective coating on an interior surface. The interior surface of a sheet of glass can be coated with a reflective coating by sputtering, in sequence, at least one dielectric layer, at least one metal layer, and at least one dielectric layer. The exterior surface of the glass can be coated with a water-sheeting coating by sputtering silica directly onto the exterior surface of the sheet of glass. Both the reflective coating and the water-sheeting coating can optionally be applied during the same pass through the same sputter coating apparatus.

Abstract:

A method and apparatus for coating two sides of a single pane of glass or other substrate in a single pass through a coating apparatus. A sputtering line is provided, this line comprising a series of sputtering chambers. At least one of the chambers comprises a downward sputtering chamber having an upper target. At least one of the chambers comprises an upward sputtering chamber having a lower target. In some embodiments, the upper and lower targets are rotary targets. The coating apparatus advantageously has a plurality of transport rollers for conveying the substrate along the sputtering line. In certain embodiments, a majority of the chambers of the sputtering line are downward sputtering chambers each having only an upper target with no lower target.
