    Abstract: The present invention is directed to improved conductive primer composition and methods. In the improved methods aspect of the present invention, a non-conductive polymeric component is precoated with a primer to render it electroconductive in preparation for electrocoating. Next, the primed polymeric component is assembled with a conductive matallic component to form a multi-material workpiece. Finally, the formed workpiece is submerged in an electrocoat bath for simultaneously electrocoating both the primed polymeric component and the conductive metallic component. In some preferred embodiments, the workpiece may be an automobile chassis.In the improved electroconductive primer compositions aspect of the present invention, such compositions comprise a dispersion of approximately 70% to 90% of a polymeric resinous binder which will cure to form a film, approximately 10% to 30% of a conductive carbon pigment, approximately 0.2 to 0.45 of an electron transmitting surfactant to provide in the cured film conductive pathways for electrons between the conductive pigment particles, and approximately 20% to 30% of a finely ground metal in alternative preferred embodiments, and a sufficient volume of solvents to provide a flowable viscosity to the primer. Such primer may be formed from a wide variety of different resins.

    Abstract: A system and process for electrodynamic powder coating of conducting and non-conducting substrates using an electrodynamic fluidized bed. The system generally includes a coating applicator means for applying charged particles to the substrate to be coated, and postcharging means for applying to the substrate an additional charge of such polarity as to cause an increase in the electrostatic forces holding the coating particles to the substrate. The system further includes a precharging means for precharging the substrate with a charge of such polarity as to effect more uniform coating of the substrate and a higher rate of coating. Where the substrate to be coated is a continuous web, the system includes a conveying means for conveying the web through the various positions adjacent to the three aforementioned means. The coating applicator means may be an electrodynamic coating apparatus of the electrodynamic fluidized bed type and comprising a fluidized bed means and a charging bed means with a porous wall positioned therebetween, and a recharging means.
