Product Overview
Indium Corporation’s sulfamate electroplating solution is available in small bottles, 55-gallon drums, or larger totes, providing flexibility to suit any production scale. This room-temperature plating bath requires minimal additives, in large part due to its efficient anode system that continuously replenishes indium metal. With proper maintenance, the bath can last for years, requiring only occasional solution top-ups.
The plating can be applied to a range of well-prepared substrate metallizations, including copper, brass, nickel, gold, tin, and mild steel. However, stainless steel and aluminum require specialized surface treatments before electroplating with any metal.
