Patent number: 6875303Abstract: The invention is a process for bonding glass to a substrate without the need to prime the surface of the substrate. The process comprises, first, treating the surface of the substrate with air plasma, applying to the surface of the substrate or to the surface of the glass an adhesive capable of bonding to the treated substrate and glass, and contacting the glass and the substrate with the adhesive disposed between the substrate and the glass, and allowing the adhesive to cure. Preferably the substrate is coated with a coating. Preferred adhesives are polyurethane or silane functional elastomeric adhesives. The process of the invention allows bonding of glass to a substrate without the need to use a primer on the substrate prior to application of the adhesive. The process is especially effective in facilitating the bonding of glass to coated substrates, especially substrates coated with acid resistant coatings such as PPG's carbamate coating or DuPont's Gen III, IV and VI coatings.Type: GrantFiled: November 26, 2002Date of Patent: April 5, 2005Assignee: Dow Global Technologies Inc.Inventors: Andon Samurkas, Ziyan Wu, Sean C.
