Application 10/832,450
adhesion to the glass while maintaining the long term bond between the
PVB sheet and the IR reflective coating. (D'Errico 861 at 2:53-3:21.)
20. D'Errico 861 refers to, and incorporates by reference U.S. Patent
5,013,779 to Fariss et al., which is commonly assigned to Monsanto Co., for
its description, at column 3, line 23 through column 4, line 15, of appropriate
PVB resins and plasticizers in the general amount of 15 to 50, preferably 25
to 40 parts plasticizer to 100 parts PVB resin (779 patent at 3:34-36).
(D'Errico 861 at 3:45-51.)
21. D'Errico 861 describes subjecting laminates to a source of intense UV
radiation—2000 hours is said to be "about equal to two years of intense
sunlight exposure as might be encountered in Arizona" (D'Errico 861
at 4:46-49)—followed by administering a Pummel Adhesion Test.
(id. at 4:65–5:15.)
22. D'Errico 861 Example 2 shows results for a laminate having a PVB
resin with 33 parts dihexyl adipate plasticizer and 0.427 parts magnesium
2-ethyl butyrate. (D'Errico 861 at 6:20–26.)
23. The following pummel adhesion results were reported for the glass on
the IR reflective side as a function of hours of UV exposure: 6(0), 5(100),
4(100), 6(1000), 5(2000); while PA results for the glass on the other side of
the PVB "were at all times between 3 and 6." (D'Errico 861 at 6:42–50.)
D'Errico 848
24. D'Errico 848 describes glass laminates comprising a heat-wave-
reflective coating and an impact-dissipating plasticized PVB sheet for
windshields and similar applications. (D'Errico 848 at 1:10–17.)
