Electrostatic painting is used to increase painting efficiency. For this purpose, it is necessary to impart conductivity to the resin surface with a surface electrical resistance value of 10 8 Ω/sq or less, and conventionally a conductive brimer is applied thereto. Conductive brushers used for electrostatic coating of synthetic resins are made by dispersing conductive fillers in a vehicle, and usually conductive fillers based on conductive carbon, zinc oxide, or tin oxide are used.
