Vehicular window assembly
First Claim
1. A vehicle window assembly for closing a window opening in a vehicle, comprising:
- a panel in the form of a sheet having first and second surfaces terminating in a peripheral edge;
a primer layer applied to a predetermined area of said first surface; and
at least one polymeric gasket applied to said sheet-like panel on at least a portion of said first surface having said primer layer, said gasket including an olefinic-styrenic copolymer and bonded to said portion of said sheet-like panel, said olefinic-styrenic copolymer of said gasket comprising a styrene content in the range from about one (1) molar percent to about fifty (50) molar percent, said primer layer comprising an olefinic-styrenic copolymer.

Abstract
A vehicular window assembly adapted to close an opening in a vehicle body includes a window panel of glass or plastic in the form of a sheet, a primer layer, and at least one polymeric gasket preferably molded to the panel on the primer layer from an olefinic-styrenic copolymer such as an ethylene-styrene copolymer or ethylene-styrene interpolymer. The primer preferably has a transition temperature above which improved adhesion characteristics are exhibited, and the panel and primer are preferably preheated above the transition temperature prior to molding or other application of the gasket. The primer may also comprise an olefinic-styrenic copolymer. Alternately, the primer can be non-cross-linkable, or cross-linkable, and is preferably cured after application of the gasket through ambient moisture and/or post heating. The gasket may also be preformed and applied to the window panel with pressure and heat, or the gasket may be extruded onto the window panel.
