Interior rear view mirror mounting system utilizing one-package structural adhesive

An interior rearview mirror mounting system for use on an automobile comprising:

• a laminated windshield;
• said windshield comprising a first bent glass panel having a front surface and a rear surface, and a second bent glass panel having a front surface and a rear surface;
• a sheet of polymeric interlayer disposed between the rear surface of said first panel and the front surface of said second panel wherein said polymeric interlayer laminates said first and second panel together, said lamination together of said first panel and said second panel being achieved by an autoclave process;
• a mirror mounting button adhered to said rear surface of said second panel by a layer of substantially cured adhesive and
• an interior rearview mirror assembly supported by said button;
• said layer of substantially cured adhesive being formed by disposing a film of a one-package, structural adhesive between said rear surface of said second panel and said mirror mounting button, and curing said film in an autoclave process to form a joint between said button and said windshield, said curing of said film and said lamination of said windshield being achieved in the same autoclave process;
• and
• said film of structural adhesive comprising an epoxy resin and a latent hardener.
