| abstract | IMPROVED CONDUCTIVE PRIMER COMPOSITIONS AND METHODS ABSTRACT OF THE DISCLOSURE The present invention is directed to improved conductive primer compositions and methods. In the improved methods aspect of the present invent-ion, a non-conductive polymeric component is pre-coated with a primer to render it electroconductive in preparation for electrocoating. Next, the primed polymeric component is assembled with a conductive metallic component to form a multi-material work-piece. Finally, the formed workpiece is submerged in an electrocoat bath for simultaneously electrocoating both the primed polymeric component and the conduc-tive metallic component. In some preferred embodi-ments, 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. |
