What are the steps in the electrocoating process?
First, electrocoating is designed to be an efficient production process. This is because of the equipment generally required to adequately support the process. Parts or components to be coated are generally transferred to a conveyor, which is part of the coating system. Steel is the most common metal to be electrocoated. For optimum corrosion protection and overall paint performance, the recommended pretreatment for steel is the zinc phosphate system. There are some variations in pretreatment steps but here is a suggested sequence of the steps for the electrocoating process over steel: Alkaline Cleaner, Water Rinse, Water Rinse, Surface Conditioner, Zinc Phosphate, Rinse, Seal, De-ionized Water Rinse, Electrocoat Application, Permeate Rinse, Final De-ionized Water Rinse, and Cure Oven.
