Abstract
A polyborosiloxane composition to be used for the formation of an insulating layer on an electric conductor comprises (A) a polyborosiloxane produced by the reaction of boric acid, a boric acid derivative, or a halogenated boron with a silane compound and a silicone oil, (B) a silicone resin or a synthetic resin having a nitrogen-containing heterocyclic ring in the molecule, (C) an inorganic filler, and (D) a common solvent for (A) and (B). An insulated electric wire excellent in thermal resistance is obtained by applying the composition to an electric conductor and baking the applied layer of the composition.
