What is E-Coating?
Upon application of the electrical potential (voltage) the paint solids are transported by electrical current from the bath to the part’s surface one molecule at a time. As the exterior surfaces of the part become coated, an electrical resistance builds. Since electricity always seeks the path of least resistance the electrical current automatically flows to areas of the part not previously coated. This process continues until all surfaces of the part are coated with the same thickness of paint solids. When the entire part is coated with the proper film thickness the flow of electricity will slow to a stop. When the electrical current stops every surface on the part is coated with a uniform thickness of paint solids.
After the paint solids are applied electrically, all runs and drips that could cause an uneven film must be removed in the post rinses. An ultra filter, which separates deionized water from the paint solids, is the basis for the closed loop post rinse system. Rinse water is continuously refiltered and reused. The excess paint, not electrically deposited, flows back to the paint tank where it can be reapplied.
Once the runs and drips have been removed, the part transfers to the dehydration and cure ovens. The dehydration oven is used to remove all water from the electrically applied paint film. After all the water is removed the part enters the cure oven. In the cure oven, the paint film undergoes a molecular transformation. The paint solids that were applied electrically now crosslink with each other and become a smooth, even, layer of acrylic modified epoxy. This epoxy film is extremely dense, thin, smooth and resistant to attack by a wide variety of chemicals.
