Electrodeposition Painting of Metal Substrates,
Abstract
Materials Research Laboratories were requested by the Armed Services to advise on the coating of steel cylinders, closed at one end. Certain limitations were made on the coating, including the stipulation that the coating was to be thin yet substantially uniform over the whole of the interior and exterior surfaces. A review of the various coating techniques indicated that the process of electrodeposition, also known as electrophoretic painting, should meet the requirements. Various water-borne electrodeposition paints based on the acrylic resins, Baycryl L461W and Cyanamid Resin XC-4010, were formulated and properties of the films deposited onto various metal substrates from these paints and from an Australian-made paint, Dulux Light Grey Electrocoat, have been studied in detail. Durable films with good adhesion, scratch and impact resistance are deposited on mild steel, on aluminium and on tin-plated panels, although the surface finish on both aluminum and tin-plate is less smooth than that on steel.
