Abstract
A breathable film cover for transparent plastic plates employed as windows and the like. A metalized plasticized polyvinyl chloride film is adhesively laminated to a polycarbonate or polyacrylate plate by means of an adhesive having a UV absorber. The plasticized PVC film allows for the escape of moisture emanating as a result of degasification of the polycarbonate or polyacrylate plates. The permeability of the PVC or polyvinyl chloride film to moisture allows the metalized plasticized polyvinyl chloride film to remain adhered to the plates without bubbles, craters or tunnels.
Claims12
A film cover for window plates that are characterized by degasification, comprising:
- a plasticized polyvinyl chloride film,
- a metalization coating adhered to said plasticized polyvinyl chloride film on one side thereof;
- an adhesive layer engaging the surface of said metalization coating that is not adhered to said plasticized polyvinyl chloride;
- and
- wherein said plasticized polyvinyl chloride film, said metalization coating and said adhesive layer are permeable to moisture escaping by degasification from the window.
A window structure, comprising:
- a polycarbonate plate;
- a plasticized polyvinyl chloride film;
- a metalization coating adhered to said plasticized polyvinyl chloride film on one side thereof;
- an adhesive interposed between said polycarbonate plate and said metalization coating for securing said plasticized polyvinyl chloride film having said metalization coating thereon to said polycarbonate plate;
- and
- wherein said plasticized polyvinyl film, said metalization coating and said adhesive are permeable to moisture escaping from said polycarbonate plate.
A window structure, comprising:
- a polyacrylate plate;
- a plasticized polyvinyl chloride film;
- a metalization coating adhered to said plasticized polyvinyl chloride film on one side thereof;
- an adhesive interposed between said polyacrylate plate and said metalization coating for securing said plasticized polyvinyl chloride film having said metalization coating thereon to said polycarbonate plate;
- and
- wherein said plasticized polyvinyl film, said metalization coating and said adhesive are permeable to moisture escaping from said polyacrylate plate.
