Palladium tank plating solution makes a great alternative to rhodium tank plating when re-plating white gold wedding and engagement rings and it can be shipped outside the UK and the EU. It is also safe for jewellery items that include elements that are made of calcium carbonate such as pearl or coral, as it doesn’t etch this kind of material. In the accompanying photograph both the silver bead and the pearl strand it was threaded on was safely immersed in the palladium solution, without the pearl being masked out. To work out how much palladium solution you will need and how long it will take, please click on the ‘Calculator’ tab above.

Back to Product Description

Main benefits;

  • Makes a great alternative to rhodium plating giving an authentic 18 carat white gold or platinum plated look.
  • palladium plating solution (unlike rhodium) doesn’t etch materials made of calcium carbonate such as pearl and coral, so you won’t have to worry about masking out these materials before submerging them in your palladium plating bath.
  • can be used as a substitute for nickel as a barrier layer for gold plating on copper and its alloys.
  • can be used as an alternative to silver as it doesn’t tarnish and is hard-wearing.
  • Very low porosity – excellent for corrosion protection.
  • Readily wettable by solder and dissolves a lot more slowly than gold in the solder making it an excellent top coat over gold for electrical contacts.
