  • Patent number: 6495251
    Abstract: A layer for protecting an underlying functional coating stack for example a single silver layer or double silver layer Low-E coating stack includes silicon oxynitride or silicon aluminum oxynitride layer. The protective film may have a uniform composition throughout its thickness i.e. homogeneous protective layer, a constantly increasing or decreasing index of infraction throughout its thickness i.e. a graded protective layer, or a combination of all or some of the foregoing i.e. a non-homogeneous protective layer. The graded and non-homogeneous layers may have an outer surface of silicon nitride, silicon aluminum nitride, silicon dioxide, silicon oxynitride or silicon aluminum oxynitride. The protective layer of the invention may be the last layer deposited on the functional coating stack or may have a film deposited thereon.

  • Publication number: 20020176988
    Abstract: A method and coating are provided for temporarily protecting a substrate or article during shipping, handling or storage by applying a removable protective coating over at least a portion of the substrate. The substrate may be flat or curved and may have zero, one or more functional coatings. A plurality of substrates with the protective coating of the invention may be arranged in a shipping container so that the protective coating reduces the possibility of damage to the substrate or optional functional coating. In one embodiment, the protective coating is the evaporation or reaction product of an aqueous coating composition containing a polyvinyl alcohol polymer which may be subsequently removed by aqueous washing, thermal decomposition or combustion. In another embodiment, the protective coating is formed by sputtering a substantially carbon coating onto the substrate. The carbon coating is subsequently removed by combustion.

  • 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.
