RHODIUM TREATMENT KIT

DESCRIPTION

Rhodium plating baths need to be prepared in a clean and well ventilated area. To achieve an ultra bright white color articles must have a nickel underplate or the finish will be unsatisfactory. Use only platinized titanium anodes when plating rhodium. Rhodium solutions must be protected from every possible source of contamination. If a solution is contaminated proper adhesion will not occur. Poor adhesion may be due to plating at too high or too low a voltage. When rhodium solutions are not in use they should be stored in a glass beaker with a snug fitting cover.
