Cataphoresis is a process in which the paint is applied by an electrophoretic method, whereby the product being painted becomes a cathode in a direct current anolyte (aqueous solution of epoxy paint) and thus attracts the colour cations. Cataphoresis represents one of the most progressive production technologies for the application of base paints with a high degree of corrosion protection to metals. The cataphoretic painting method is considered one of the most advanced technologies for surface treatments of metal products. Currently, cataphoresis has no comparable competition in a series of production areas. The largest contribution to the cataphoresis technology development has been made by the automotive industry, where the corrosion resistance of bodywork and other components has been the focus of interest for all manufacturers. The high quality of the surface treatment, together with the economic and environmental advantages, have predetermined this technology to be used in other areas of the mechanical engineering and consumer goods industries.
