Pre- and Post- Treatment Processes

Anti-tarnish protection for perfect surfaces

Tarnishing is an increasingly important issue: layers are getting thinner, yet the demands increase.
It is important to avoid corrosion or discoloration. What you need is effective protection for both decorative as well as for technical products - without any compromising about the contact resistance.

Umicore offers two highly innovative anti-tarnish solutions: Umicore Sealing 691 EL - our protection for technical products - and Umicore Antitarnish 616 PLUS, our premium solution for decorative applications.
