Abstract
An apparatus for supplying a two-component, electrically conductive coating material which includes a first flow path for supplying a metered quantity of a catalyst from a source to a mixing device, a second flow path for applying a metered quantity of resin from a source to the mixing device, a third flow path for transferring the resulting two-component coating material from the mixing device to at least one coating dispenser which discharges electrostatically charged coating material onto a substrate, and, at least one voltage block device for maintaining a continuous voltage block between the electrostatically charged coating material and the sources of catalyst and resin.
