Palli EX plating solution is a pure palladium plating solution for decorative use. It produces a white, bright finish that can almost substitute for rhodium. The Palli EX can be applied directly to nickel, silver, gold, and copper based alloys. The process is similar to that of rhodium, using platinized titanium anodes. Palladium is commonly used as a flash before rhodium plating, and is used by many manufacturers for a final finish.
