Electroplating refers to a surface processing method, in which a cathode part having the surface of a base material to be plated and the salt solution containing the corresponding metal cation, when the voltage is applied in the electric circuit, it deposits the metal cation on a surface of the base material through electrolysis. Electroless plating, also known as chemical plating or autocatalytic plating, is a plating method in which metal ions in a plating solution are reduced to metal and deposited on the surface of a part without an applied current by employing a suitable reducing agent. TMG Chemicals can provide customers with a variety of metal salts and additives, widely used in tin plating, copper plating and other industries.
