Abstract: An electrodeposition method wherein a conductive substrate such as, for example, a metal fastener is first coated by means of an anodic electrodeposition process, then subjected to thermal curing, and then subjected to a cathodic electrodeposition process. The anodic electrodeposition process is carried out until the coating insulates the substrate at which point the coating process stops. The curing step lowers the dielectric strength of the anodically deposited coating, thereby allowing the substrate to accept a cathodically deposited top coat. The resultant coated substrate demonstrates superior corrosion resistance properties and improved cosmetic appeal.
