Electrocoating: A Technical Review, 1990 Polymers, Laminations & Coatings Conference Proceedings
This paper is a review of the electrodeposition process whereby electric power is utilized to coat articles with conductive surfaces. Coatings are formulated with charge bearing organic polymers dispersed in an aqueous medium and stabilized to provide films of homogeneous compositions. This process, which is also referred to as electrocoating, is widely used in the automotive industry to prime the metal frame of car bodies. This technology is now being developed and commercialized in the rigid packaging industry. In our laboratory, experiments have been conducted to coat aluminum coils to fabricate ends for beer cans. Electrocoating techniques are also being developed to coat the inside and outside of metal cans simultaneously.
