Claim:
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 hinge mounting portion of said first surface of said glass panel; providing a hinge attachment member; providing an isocyanate component, said isocyanate component comprising filler; providing a polyol component, said polyol component comprising at least one plural amine compound containing at least three amine groups, said polyol component further comprising phenyl diethanolamine and said polyol component further comprising filler; providing a first primer, said first primer comprising at least one adhesion promoting compound and further comprising at least one volatile solvent; providing a second primer, said second primer comprising a single-component urethane primer; applying said first primer to coat at least said fritted hinge mounting portion 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; applying said second primer to coat at least said primed fritted hinge mounting portion of said first surface of said glass panel; mixing said isocyanate component and said polyol component in a static mixer to form a mixed two-component urethane adhesive; joining said hinge attachment member to said doubly primed fritted hinge mounting portion with said mixed two-component urethane adhesive sandwiched therebetween; mechanically maintaining said joining of said hinge attachment member to said doubly primed fritted hinge 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 hinge attachment member and said doubly primed fritted hinge mounting portion to cure to form a layer of cured urethane adhesive bonding said attachment member to said first surface of said glass panel prior to installation of said assembly in the vehicle and without exposure of said bonded attachment member on said second surface of said panel; wherein said cured adhesive layer disposed between said attachment member and said glass panel has a thickness in the range from about 0.25 mm to about 2.0 mm; and wherein said assembly comprises one of an articulatable liftgate vehicular window assembly and an articulatable vehicular side window.
