  • Patent number: 6579427
    Abstract: Multilayer high transmittance, low emissivity coatings on transparent substrates feature a special antireflective base film of at least two parts on the substrate-near side of a metallic, reflective film. A first of the two parts is in contact with the metallic film. This first film-part has crystalline properties for causing the metallic film to deposit in a low resistivity configuration. The second of the two film-parts supports the first part and is preferably amorphous. Coated articles of the invention also feature, in combination with the above-mentioned base film or independently thereof, a newly discovered, particularly advantageous subrange of thicker primer films for coated glass that can be thermally processed for tempering, heat strengthening, or bending.

  • Publication number: 20020136905
    Abstract: The present invention is directed to a low emissivity, low shading coefficient, multi-layer coating and coated article having a luminous transmission of less than about 70 percent, a shading coefficient less than about 0.44 and a solar heat gain coefficient of less than about 0.38 and a ratio of luminous transmittance to solar heat gain coefficient of greater than about 1.85. The coated article, e.g. an IG unit, has a substrate with at least one antireflective layer deposited over the substrate. At least one infrared reflective layer is deposited over the antireflective layer and at least one primer layer is deposited over the infrared reflective layer. Optionally a second antireflective layer is deposited over the first primer layer and optionally a second infrared reflective layer is deposited over the second antireflective layer.

  • Patent number: 5942338
    Abstract: Multilayer high transmittance, low emissivity coatings deposited over transparent substrates have improved mechanical durability, e.g. scratch resistance by the inclusion of at least one mechanical durability enhancing layer (hereinafter "MDE layer"). The MDE layer includes one or more pairs of a zinc oxide sublayer having deposited thereover a sublayer of an oxide of zinc and tin. In one embodiment of the present invention, the MDE layer is composed of two sublayers which includes a first sublayer of an oxide of zinc having deposited thereover a second sublayer of an oxide of zinc and tin. In another embodiment of the invention, the MDE layer is composed of four sublayers which includes a first sublayer of an oxide of zinc, having deposited thereover a second sublayer of an oxide of zinc and tin, having deposited thereover a third sublayer of an oxide of zinc, having deposited thereover a fourth sublayer of an oxide of zinc and tin.

  • Patent number: 5414240
    Abstract: An electrically heatable windshield with a hidden bus bar configuration. A border of opaque ceramic material, preferably a lead borosilicate enamel, is bonded to an interior surface of the transparency about its periphery. Opposing electroconductive bus bars, preferably a low frit content silver-containing ceramic material, are bonded to the ceramic material so that the entire inner edge of the bus bar overlays a portion of the ceramic material and is spaced from the inner edge of the border, providing an intermediate portion of the border between the bus bars and transparency surface that is not covered by the bus bars. An electro-conductive coating is applied to the transparency to interconnect the bus bars and covers to the inner surface of the transparency, the bus bars and the intermediate portion of the ceramic material border so that electric current flowing between the bus bars must flow through the portion of the coating that covers the intermediate portion of the border.
