Method of paint application in which an electrically conductive article to be coated is made one
of the electrodes in a tank of water-thinned paint. The other electrode is generally a metal. The
two electrodes are connected to a source of electrical power, the polarity of the article to be
coated being of the opposite sign to that of the particles in the liquid paint in the tank. The
charged particles move towards the articles under the influence of the electric field, and when
they give up their charge at the electrode (article), they are deposited and ultimately form a
continuous film of paint.
