Patent number: 7309745Abstract: A silicone coating material is operative to graft a silicone polymer coating on an ignition wire. The ignition wire includes an insulated conductor with an inner conductive core and an outer insulating jacket layer which has an outer surface. The silicone coating material is applied to the outer surface of the insulating jacket layer and includes a silicone prepolymer, a coupling agent, a catalyst, and a graft initiator. The graft initiator is operative to prepare the outer surface of the insulating jacket to receive by grafting the coating layer including the silicone prepolymer and the coupling agent, and the catalyst is operative to promote grafting by polymerization of the coating layer.Type: GrantFiled: July 5, 2005Date of Patent: December 18, 2007Assignee: Federal-Mogul World Wide, Inc.Inventors: Mohan L. Sanduja, Paul Thottathil, Lina Zilberman

Patent number: 7307134Abstract: This invention relates to silylated polymers having mixed alkoxy groups on the silyl portion thereof, methods of their preparation, and compositions and reaction products formed therefrom. These alkoxysilylated polymers can be crosslinked when exposed to atmospheric moisture to become useful elastomers, sealants or adhesives. The presence of different alkoxy groups on the silicon atoms can control or otherwise moderate the cure speeds of these silylated polymers.Type: GrantFiled: February 22, 2002Date of Patent: December 11, 2007Assignees: Henkel Corporation, Henkel KGaAInventors: Thomas F. Lim, Thomas Bachon, Bernd Beuer, Johann Klein
