    Brilliant-white and ultra-bright rhodium coatings

    RHODUNA® Diamond Bright deposits brilliant-white, ultra-bright coatings of previously unattained lightness and brilliance. It is additionally characterized by high covering speed and excellent throwing power. Furthermore the RHODUNA® Diamond Bright layer thicknesses of up to 5 μm can be deposited crack-free.

    Rhodium can be directly deposited on silver, gold, copper and copper alloys, nickel and nickel alloys. The layers are extremly low-porous and therefore very corrosion resistant.
