  • Publication number: 20140227512
    Abstract: The invention provides methods for forming silicon oxide-containing layer(s) on a substrate, such as glass, by heating a substrate, vaporizing at least one precursor comprising a monoalkylsilane having an alkyl group with greater than two carbon atoms to form a vaporized precursor stream, and contacting a surface of the heated substrate with the vaporized precursor stream at about atmospheric pressure to deposit one or more layers comprising silicon oxide onto the surface of the substrate. The invention is particularly useful for applying an anti-iridescent coating to glass in an online float glass process.

  • Publication number: 20140166922
    Abstract: Disclosed is a combination of hydrofluoroolefins and/or hydrochlorofluoroolefins with stabilizers wherein the stabilizers minimize the degradation of the hydrofluoroolefins and hydrochlorofluoroolefins during storage, handling and use yet allow for atmospheric degradation. The combinations exhibit low or zero ozone depletion potential and lower global warming potential making them of interest as replacements for chlorofluorocarbons and hydrofluorocarbons. The combinations of the present invention comprise hydrofluoroolefins and/or hydrochlorofluoroolefins in combination with a stabilizer or stabilizers selected from free radical scavengers, acid scavengers, oxygen scavengers, polymerization inhibitors and combinations thereof.

  • Publication number: 20140158185
    Abstract: The invention relates to a multi-layer weatherable film structure having an outer layer of a highly weatherable film, a layer having a high thermal deformation temperature, an optional tie layer, and a thin layer of polyolefin or polyamide. The highly weatherable film layer preferably is polyvinylidene fluoride. The polyolefin or polyamide layer is less than 500 microns in thickness, and preferably the whole film structure is less than 750 microns thick. The polyolefinjpolyamide side of the film structure can easily be adhered to many different substances—especially polyolefins and polyamides. This film can be used to provide a highly weatherable protective layer a substrate. One useful application for the film is in a photovoltaic module to protect the back side of the module from weathering and abrasion. The multi-layer film structure can be adhered to a typical polyolefin-based encapsulant layer and used as a backsheet encapsulant in a photovoltaic module.
