Bonded vehicular glass assemblies utilizing two-component urethane adhesives to attach dynamic load-bearing attachment members to glass substrates to form a joint suitable for use on a vehicle, and related methods of forming are described herein. In addition, methods of attaching components to glass by use of these adhesives are disclosed. The method of forming the assemblies may include priming the glass panel prior to applying the adhesive to the primed glass panel and/or attachment member. The method may include allowing the urethane adhesive to cure to form a layer of cured urethane adhesive bonding the attachment member to the first surface of the glass panel without exposure of the bonded attachment member on the second surface of the panel. The cured adhesive layer disposed between the attachment member and the glass panel may have a thickness in the range from about 0.25 mm to about 2.0 mm.

A method for manufacturing an articulatable vehicular window assembly suitable for use in a vehicle, said method comprising: providing a glass panel weighing at least 5 kilograms and having a first surface and an opposing second surface, said glass panel comprising a curved, tempered glass panel and wherein said first surface comprises a concave curved surface and wherein said second surface comprises a convex curved surface; said glass panel provided coated with a light absorbing frit layer at least at a first hinge mounting portion of said first surface of said glass panel and provided coated with a light absorbing frit layer at least at a second hinge mounting portion of said first surface of said glass panel, wherein said second hinge mounting portion of said first surface of said glass panel is spaced from said first hinge mounting portion of said first surface of said glass panel; said glass panel provided coated with a light absorbing frit layer at least at a first strut mounting portion of said first surface of said glass panel and provided coated with a light absorbing frit layer at least at a second strut mounting portion of said first surface of said glass panel, wherein said second strut mounting portion of said first surface of said glass panel is spaced from said first strut mounting portion of said first surface of said glass panel; providing a first hinge attachment member and providing a second hinge attachment member, each of said hinge attachment members having a respective mounting component, said respective mounting component having a surface area greater than two square inches; providing a first strut attachment member and providing a second strut attachment member, each of said strut attachment members having a respective mounting component, said respective mounting component having a surface area less than six square inches; providing an isocyanate component, said isocyanate component comprising filler; providing a polyol component, said polyol component comprising filler, wherein said polyol component comprises at least one plural amine compound containing at least three amine groups, said polyol component further comprising phenyl diethanolamine; providing at least a first primer, said first primer comprising at least one adhesion promoting compound and further comprising at least one volatile solvent; applying said first primer to coat at least said respective fritted hinge mounting portions and said respective fritted strut mounting portions of said first surface of said glass panel; allowing said at least one volatile solvent of said first primer to at least partially flash off at each of said respective primed fritted hinge mounting portions and strut mounting portions of said first surface of said glass panel; mixing said isocyanate component and said polyol component to form a mixed two-component urethane adhesive; joining said respective mounting component of said respective hinge attachment members and strut attachment members to said respective at least first primed fritted hinge mounting portion and primed fritted strut mounting portion with said mixed two-component urethane adhesive sandwiched therebetween; mechanically maintaining said joining of said respective mounting component of said hinge attachment members and said strut attachment members to said respective at least first primed fritted hinge mounting portion and at least first primed fritted strut mounting portion for a time sufficient for the mixed two-component urethane adhesive sandwiched therebetween to achieve an at least partial set; allowing said mixed two-component urethane adhesive sandwiched between said respective mounting components of said hinge attachment members and said strut attachment members and said respective at least first primed fritted hinge mounting portions and at least first primed fritted strut mounting portions to cure to form respective layers of cured urethane adhesive bonding said respective attachment member to said first surface of said glass panel prior to installation of said assembly in the vehicle and without exposure of said mounting component of said respective bonded attachment members on said second surface of said panel; wherein said respective cured adhesive layer disposed between said respective mounting component of said attachment members and said glass panel has a respective thickness in the range from about 0.25 mm to about 2.0 mm; wherein said assembly comprises an articulatable liftgate vehicular window assembly; and wherein said first primer is applied to said respective frit layer entirely over the area to which said respective mounting component of said respective attachment member bonds. 66. The method of claim 65 further comprising providing a latch attachment member having a latch mounting component and joining said latch mounting component of said latch attachment member to a latch mounting portion at said first surface of said glass panel with said mixed two-component urethane adhesive sandwiched therebetween.
