US Patent:
4028475, Jun 7, 1977
Filed:
May 21, 1975
Appl. No.:
5/579388
Inventors:
Michael E. Willdorf - Malden MA
Assignee:
Material Distributors Corporation - Woburn MA
International Classification:
B32B 1708, B60J 106, B60J 300, B32B 1508
US Classification:
428215
Abstract:
A security film for shatterproofing windows comprises: at least two oriented polyethylene terephthalate self supporting strata having critical thicknesses for shock absorption and tensile strength, of which at least one optionally has a semi-transparent vapor deposited aluminum coat for solar control; and at least two relatively soft bonding strata having critical thicknesses for adhesion and cohesion, of which at least one is an internal copolyester stratum for bonding self supporting strata together and one is a pressure sensitive stratum at the outer surface of the film for application to window glass.

US Patent:
RE28883, Jun 29, 1976
Filed:
Sep 22, 1975
Appl. No.:
5/615376
Inventors:
Michael E. Willdorf - Malden MA
Assignee:
Material Distributors Corporation - Woburn MA
International Classification:
B32B 1706
US Classification:
156 71
Abstract:
[. A solar control film for application to window glass comprises a vapor deposited aluminum coat, which partially transmits light, interposed between a pair of moisture permeable polymeric strata, each of which is self supporting. In one modification, an optional outer coat on one of the polymeric strata is composed of a pressure sensitive adhesive in association with a silicone release sheet. In another modification, an optional outer coat on the other of the polymeric strata is composed of a silicone release agent. ]. . Iadd. A process for applying a solar control film to window glass, the solar control film comprising a pair of self supporting polyester support strata, a vapor deposited aluminum stratum and an internal bonding stratum interposed therebetween, and an external bonding stratum of pressure sensitive composition on an external face of one of the polyester support strata, the process comprising the steps of applying the solar control film to the window glass with an aqueous liquid therebetween, squeegeeing the solar control film to the window glass and permeating water through the solar control film from the region between it and the window glass. Iaddend.

International Classification:
B32B 1508, C09J 702
US Classification:
428215
Abstract:
A solar control film, for application to window glass by the consumer with minimum or no preparation, comprises a vapor deposited aluminum coat, which partially transmits light, interposed between a vinyl stratum and a polyester stratum, either of which contains an ultraviolet inhibitor and each of which is self supporting. This film is adhered by pressing the surface of its vinyl stratum against the window glass in either dry or wet condition.
