  • Patent number: 8524840
    Abstract: In one aspect, this invention is a composition comprising a urethane prepolymer having isocyanate moieties; a catalytic amount of a compound which catalyzes the reaction of isocyanate moieties with water or an active hydrogen containing compound; alpha hydrocarbyl silane compound; and a catalytic amount of a compound which catalyzes silanol condensation. The composition of the invention can be used to bond a window into a structure without the need to prime the window or the window flange of the structure.

  • Patent number: 7789990
    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.

  • Patent number: 7345130
    Abstract: The invention is an adhesive composition comprising a) one or more silane functional prepolymers comprising a polyether or a polyolefin backbone and silane moieties capable of silanol condensation; b) one or more isocyanate functional prepolymers comprising a polyether backbone and isocyanate moieties; c) one or more organotin compounds or titanate or zirconate compounds having one or more ligands comprising a hydrocarbyl phosphate ester or a hydrocarbyl sulfonate ester, or a mixture thereof; d) a tertiary amine or an anhydrous strong organic acid which is miscible with the polymer and enhances the bonding of the adhesive to a coated unprimed substrate. In one embodiment, the invention is a method of bonding two or more substrates together using the adhesive compositions of this invention. The process comprises applying an adhesive as described herein to one or more of the substrates; contacting the one or more substrates with the adhesive disposed between the substrates; and allowing the adhesive to cure.
