Rhodium electrolytes
Rhodium baths from METAKEM produce extremely bright, brilliant white surfaces on silver, gold, and white gold. In addition to the shine and extraordinarily white color, the corrosion resistance as well as high abrasion resistance and hardness of this precious metal are valued in electroplating. Rhodium plating of silver provides lifelong tarnish protection while maintaining the natural silver luster. The use of uniquely high-quality rhodium baths is essential for both the production of high-end jewelry and the manufacture of reed contacts.
Strongly acidic rhodium bath for the electroplating of brilliant white rhodium layers. With Rhodium-Decor-S2, L-values of ‹ 90 on the color scale are achieved.
