RH2B is a ready-to-use black rhodium for bath plating. This black rhodium electrolyte has been designed specifically for decorative electroplating applications by granting alternative color options for finishes. The final color produced can be considered black with yellow undertones which makes the black color appear deeper. This room temperature procedure makes it ideal for two-tone designs as high temperature plating processes typically destroy traditional plating masks. RH2B can be replenished and maintained by completely restoring the rhodium content and the color with an all inclusive replenisher. The formulation is 100% arsenic free both in the metal deposited and in the chemical itself and falls within REACH compliance.
