5.1 Paints electroplated by the action of an electric field (oven drying)

The industrial development of electrophoretic paints began in the 1980s for three main reasons:

• increase the corrosion resistance of metallic materials by making it easier to paint hollow bodies;

• increased productivity ;

• improved working conditions thanks to the elimination of solvent vapours during application. The paint deposit is obtained by immersing the parts in a water-soluble binder as soon as an electric field is applied.

Electroplating is achieved either by cataphoresis or anaphoresis, depending on the chemical nature of the binder. These deposition processes...
