METHOD OF COATING ELECTRIC WIRE AND INSULATED WIRE

摘要

It is an object of the present invention to provide a method of coating an electric wire by which an insulated wire having a high dielectric breakdown voltage can be obtained. A method of coating an electric wire, comprising a step (I) of forming a first insulating film by cationic electrodeposition using a cationic electrocoating, and a step (I I) of forming a second insulating film on the first insulating film formed in the step (I) using an insulating coating, said cationic electrocoating containing a resin composition of which a hydratable functional group is reduced directly by an electron and passivated, resulting in deposition of a film
