Abstract: A coating composition is provided herein prepared by dispersing in water a film-forming component comprising about 60-99 wt. % of a powder containing as a main component one or more resins selected from polyethylene, polypropylene and their derivatives and about 1-40% by weight of a low molecular weight oxidized polyethylene and/or derivatives thereof. This coating can be used for coating various electrical parts, automobile parts, etc., and the coatings have an excellent appearance, good chemical resistance, high insulation properties and good water resistance.

Abstract: This invention is directed to coating compositions for electrocoating electroconductive substrates for printed circuits comprising a pigment-containing finely divided synthetic resin powder in which the resin comprises an epoxy resin, and the pigment comprises pigments with 2-10 weight parts of finely divided silica, admixed with a water-dilutable cationic resin, and to methods of utilizing the composition for forming an insulating film on an electroconductive substrate.
