Electro-Deposition Painting (E-Coat)
Electro-deposition painting, or E-Coat, is an organic coating deposited from an aqueous solution through an electrical charge. Materials with a positive electrical charge are drawn to parts that are negatively charged. When energized, the part attracts oppositely charged paint particles. The surfaces and edges of the painted parts are covered with an evenly deposited film. The parts are then baked in ovens at 380º, with the deposited particles flowing out to become a continuous organic film.
