CATHODIC AUTOMOTIVE ELECTRODEPOSITION (PAINT)

Cathodic electrodeposition as a means of applying organic primer coatings in the automotive industry offers the following advantages: superior corrosion resistance over steel and other substrates; high throw-power; lower curing schedules, and long-term stability. Other advantages are that the system is automated, film is uniformly thick, there is almost 100% utilization of paint, and the paint is nonflammable. Equipment requirements of cathodic paint are similar to or identical with those of anodic paint in many ways. Operation of cathodic systems are also similar in many respects to anodic systems, but control parameters such as pH, MEQ, voltage, and conductivity are different. There are numerous cathodic electrodeposition systems in operation in the automotive industry.
