Abstract:
1. A silicone coating material operative to graft a silicone polymer coating on an ignition wire, the ignition wire having an insulated conductor comprising an inner conductive core and an outer insulating jacket layer having an outer surface, on the outer surface of the insulating jacket layer, comprising: a silicone prepolymer; a coupling agent; a catalyst, and a graft initiator, wherein the graft initiator is operative to prepare the outer surface of the insulating jacket to receive by grafting a coating layer comprising said silicone prepolymer and said coupling agent, and wherein said catalyst is operative to promote grafting by polymerization of the coating layer; wherein said silicone prepolymer comprises an RTV silicone resin solution, said RTV silicone resin solution comprises a methyl siloxane resin solution, and said methyl siloxane resin solution comprises, by weight, >60% octamethyltrisiloxane, 15.0-40.0% dimethyl methylphenylmethoxy siloxane, 3.0-7.0% methyltrimethoxysilane and 3.0-7.0% toluene.
