Abstract
Abstract A process for the electrophoretic coating or repair of flaws in insulation of electrical components which employs non-aqueous solutions comprising liquid nitroalkanes as a solvent, consisting essentially of a resin dissolved in the solvent together with surface active agents, and desirably containing small amounts of a finely divided inorganic filler, to provide improved coverage on sharp edges of members being coated. The electrophoretically applied coating is then heat treated.
