Abstract
The invention provides transparent conductive coatings based on indium tin oxide. The coating has an oxide overcoat, such as an alloy oxide overcoat. In some embodiments, the coating further includes one or more overcoat films comprising silicon nitride, silicon oxynitride, silicon dioxide, or titanium dioxide.
Claims22
A multiple-pane insulating glazing unit having a between-pane space and two opposed external pane surfaces, a desired one of the two external pane surfaces bearing a coating comprising both an indium tin oxide film and an aluminum tin oxide film, the aluminum tin oxide film being located over the indium tin oxide film, the aluminum tin oxide film being in direct contact with the indium tin oxide film, wherein the aluminum tin oxide film is an exposed outermost film of the coating, and wherein the aluminum tin oxide film contains tin at a weight percent, on a metal-only basis, of from 50 to 90 percent.
