Electropheretic coating, sometimes referred to as e-coating or electropainting, is a general term describing the application of organic coatings to electrically conductive substrates through the use of electric currents. As one might imagine, there are a vast number of formulations and techniques within the whole field of electrophoretic coatings. Typically, these coatings use a resin combined with either epoxy or acrylic to complete the formulation. Additionally, these coatings can be further categorized into two groups, which determines that the item to be coated is either anodic (+) or cathodic (-) in a direct current circuit. For the sake of this paper we will explore the possible advantages of removing traditional elements found in coatings such as epoxy or acrylic, replace them with nano-particles in a ceramic form, apply them by the means of a cathodic coating circuit, and run comparative trials to the most commonly used decorative applications in the industry today.
