Umicore Antitarnish 616 PLUS
Heavy metal free Antitarnish process for silver
Umicore Antitarnish 616 is a medium based on nano-technology for protecting silver against tarnishing. Special nanopolymers absorb on the silver surface and cross-link to form a protective layer of a few nanometers thickness. The invisible layer protects the base material from oxidation and discoloration.
Through the additional use of Umicore Antitarnish 616 Makeup Salt PLUS, as well as the application of an electrical voltage, Umicore Antitarnish 616 can be applied even better and more securely to the surfaces to be protected. Thus, not only silver surfaces, but also other metallic surfaces can be protected from oxidation and discoloration. In comparison with antitarnish processes available on the market, it is possible to improve the resistance of protected silver surfaces enormously, e.g. in 2% K2S solutions.
