New Skin-friendly Umicore Antitarnish 616

The new protective coating from Umicore Electroplating is well suited for gold, silver, rhodium, platinum as well as palladium and is based on advanced nano-biotechnology. When treated, such surfaces benefit from long lasting wear resistance. This non-metallic, water-based protective finish is applied via simple immersion of the material, which is then protected from oxidation and discoloration without compromising the material’s soldering characteristics.
Umicore Antitarnish 616 is suitable for rack or barrel processing, is gentle to the skin and is also hypoallergenic. In addition, it protects against scratching and abrasion and is also stain- and water-resistant. Even when used as a secondary treatment, sanding and polishing don’t damage this protective coating. Plus, this coating is almost invisible and the precious metal remains recyclable.
Best Ratings: The Umicore Antitarnish 616 also achieved the best results during ammonium polysulfide testing. And it showed a significantly higher durability than any other comparable product on the market today. Similar results are usually only reached by chromate coatings.
