The electrophoretic coating process using EC-3388 at low baking temperaturesallows for the deposition of a transparent acrylic/polyurethane resin coatingonmetal surfaces. After drying and curing, it forms a clear, durable protectivelayer. The coating thickness is evenly distributed, and its pencil hardness canreach4H. The EC-3388 process utilizes cathodic electrophoresis to deposit theresincoating, which adheres to most conductive metal surfaces, includingbrass, bronze (copper-tin alloy), stainless steel, gold, silver, nickel, titanium, magnesium, and aluminum. It is particularly suitable for hardware componentsin furniture, luggage, jewelry, and lighting fixtures.
