Definitions

  • the metal layer may comprise a series of alternating layers of metal oxide and metal.
  • the metal oxide may include indium oxide or indium tin oxide.
  • the metal may comprise silver.
  • the layer of laminating adhesive that includes the corrosion inhibiting material may comprise between about .01% and about 5% by weight corrosion inhibiting material.
  • Silver layers are highly prone to corrosion in the presence of atmospheric elements such as water and chlorine, especially along the exposed edges of the window film. That is, even though the layer of silver in a window film construction may be protected by a coating or a laminated film, the silver layer will be exposed to the corrosive elements of the surrounding environment along its edge. The corrosion process is accelerated with increased ambient temperature in the presence of, for example, salt and moisture. Corrosion is aesthetically undesirable and also interferes with the performance characteristics of the window film. To protect the silver layer from corrosion, the silver layer is often alloyed or sandwiched between layers of other metals, such as copper or gold. These corrosion protection methods, however, add cost to the window film, alter the appearance and optical transmission of the window film, and decrease the conductivity of the metal layer.
  • a window film having low reflection in the visible part of the solar spectrum (400 - 800 nm) is desirable while maintaining a high degree of reflection in the near IR range (800 nm - 2500 nm).
  • Multi-layer window film constructions having a dielectric/metal/dielectric layer in an A/B/A/B.... type sequence may be made by tailoring the thickness of the individual layers such that the reflection in the visible range is suppressed.
  • Such films are described in, for example, U.S. Patents 6,007,901 (Maschwitz, et al.) and 6,391,400 (Russell, et al).
  • FIG. 2 is an enlarged cross sectional view of an alternate embodiment of the invention.
  • Suitable corrosion inhibiting materials include mercaptoacetic acid, 3- mercaptopropionic acid, 11-mercaptoundecylic acid, thiophenol, diphenyl disulfide, N-(2- hydroxyethyl)mercaptoacetamide, 2,2'-dimercaptodiethyl ether, 2,2'-dimercapto diethyl thioether, 1 ,2-ethanedithiol, and 3-mercaptopropyl trimethoxysilane, glycol bis(3- mercaptopropionate), trimethylolpropane tris(3-mercaptopropionate), octadecyl mercaptan, dicetyl disulfide, octadecyl thioglycolate, 1-octaddecane thiol (ODT), trimethylol propane tris(3- mercapto propionate) (TMP), 5-methyl-lH- benotriazo
  • the quantity of corrosion inhibitor present in the adhesive will be the amount needed to achieve the desired level of corrosion resistance for the metal layer without compromising the desired properties of the adhesive.
  • the window film 20 includes a release liner 22 arranged over a layer of mounting pressure-sensitive adhesive (PSA) 26 that serves to adhesively bond the window film 20 to a substrate surface, such as a pane of window glass.
  • PSA mounting pressure-sensitive adhesive
  • the liner 22 may be, for example, a layer of one mil polyethylene terephthalate (PET).
  • PET polyethylene terephthalate
