Abstract
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.

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.
