Silane functional adhesive composition and method of bonding a window to a substrate without a primer
Abstract:
The invention is an adhesive composition comprising one or more polymers having a flexible backbone and silane moieties capable of silanol condensation; one or more hydrophobic silanes having one or more hydrocarbyloxy groups and one or more hydrocarbyl groups; one or more catalysts for the reaction of silane moieties with active hydrogen containing compounds. Preferably, the adhesive composition further comprises one or more heat stabilizers and/or light stabilizers. In another embodiment, the invention is a method of bonding a window to a coated substrate, such as a window in a vehicle, which comprises applying to the window or the coated substrate an adhesive as described; contacting the window with the coated substrate wherein the adhesive is located between the window and the substrate; and allowing the adhesive to cure.
