An electrically conductive protective coating or film is provided over the surface of a reflective coating of a solar mirror by flowing or directing a cation containing liquid and an anion containing liquid onto the conductive surface. The cation and the anion containing liquids are spaced from, and preferably out of contact with one another on the surface of the reflective coating as an electric current is moved through the anion containing liquid, the conductive surface between the liquids and the cation containing liquid to coat the conductive surface with the electrically conductive coating.

Electrocurtain coating process for coating solar mirrors

The present invention is directed toward a method for coating an article by placing the article in a coating apparatus comprising at least one coating chamber having at least one air conduit in flow communication with the coating chamber via an air pathway. A portion of the article extends into a shielding member. At least one coating member is positioned in the coating chamber and is in flow communication with a source of titanium-containing coating material. The coating member deposits the coating material onto the exterior of the article to form a coating. At least one exhaust member is in flow communication with the coating chamber via an exhaust pathway for removing excess coating material from the coating chamber.

A coated article comprising a substrate and a copper oxide and manganese oxide coating over the substrate, the coating having the molar ratio of copper to manganese in the range of about 6.8 to 1.2 and a blue color in transmission is disclosed.

Compositions and methods for forming coatings of selected color on a substrate and articles produced thereby

A coated substrate is disclosed. The coated substrate includes a substrate; an undercoating having one or more materials selected from tin oxide, silica, titania, alumina, zirconia, zinc oxide and alloys and mixtures thereof nitrides of titanium, zirconium, hafnium, silicon, aluminum and mixtures thereof, and oxy-nitrides of titanium, zirconium, hafnium, silicon, aluminum and mixtures thereof overlaying at least a portion of the substrate; and a functional coating overlaying at least a portion of the undercoating. As a result of the undercoating, the coated substrate can exhibit improved properties such as improved aesthetic properties, increased durability, photocatalytic activity, mechanical durability, etc.

Coated substrates that include an undercoating

A method and article are disclosed wherein a substrate is provided with a photocatalytically-activated self-cleaning surface by forming a photocatalytically-activated self-cleaning coating on the substrate by spray pyrolysis chemical vapor deposition or magnetron sputter vacuum deposition. The coating has a thickness of at least about 500 Angstroms to limit sodium-ion poisoning to a portion of the coating facing the substrate. Alternatively, a sodium ion diffusion barrier layer is deposited over the substrate prior to the deposition of the photocatalytically-activated self-cleaning coating to prevent sodium ion poisoning of the photocatalytically-activated self-cleaning coating. The substrate includes glass substrates, including glass sheet and continuous float glass ribbon.

Photocatalytically-activated self-cleaning article and method of making same

A copper containing component and a manganese containing component are applied onto the surface of a substrate to form a coating having a selected ratio of copper to manganese to form a desired color. For a brown color, the film molar ratio of copper to manganese is above 1; for an amber color, the molar ratio is below 1, and for a blue color the film molar ratio is about 1. Further, color shifting of a multi-component coating upon subsequent heat treatment is minimized or prevented by determining the most mobile species in the coating and then placing a concentration gradient layer of an oxide of that mobile species between the substrate and the coating.

The present invention is directed to a method of and apparatus for forming a coating having at least one fade zone over a substrate. The method and apparatus include positioning a coating composition dispenser above a surface of a substrate with the coating composition dispenser oriented to dispense a coating composition spray generally normal to the surface of the substrate. A gas dispenser is also positioned above the surface of the substrate and adjacent the coating composition dispenser with the gas dispenser oriented to dispense a gas stream generally normal to the surface of the substrate. The coating composition spray and the gas stream are spaced from each other so as to develop an interference effect therebetween adjacent the surface of the substrate. Preferably the substrate is maintained at a temperature which pyrolyzes the coating composition. The interference effect directs the coating composition to deposit over the substrate as a coating having a fade zone. In an alternative embodiment of the present invention, a plurality of coating composition dispensers and gas dispensers may be positioned over the substrate to provide one or more coatings on the substrate, each of which possesses at least one fade zone.

A neutral, dark gray, soda-lime-silica glass having luminous transmittance less than 35 percent, infrared transmittance less than 20 percent, and total solar energy transmittance less than 22 percent (all at 3.9 millimeter thickness) is produced with colorants consisting essentially of 1.0 to 2.2 percent by weight total iron, at least 0.20 percent FeO, 0.01 to 0.03 percent CoO, and 0.0005 to 0.005 percent Se. The flat glass product having such a composition is particularly suitable for use as privacy glazing. The use of the glass as a substrate for a reflectively coated product is also disclosed. A low transmittance, reflective coated article is disclosed comprising a soda-lime-silica glass substrate having luminous transmittance less than 35 percent, infrared transmittance less than 20 percent, and total solar energy transmittance less than 22 percent (all at 3.9 millimeter thickness) and a metal oxide coating having a luminous reflectance not more than 25 percent from the coated surface, and not more than 8 percent from the uncoated surface. The low transmittance coated glass product is particularly suitable for use as privacy glazing.
