Reliable protection for technical precious metal surfaces
Umicore Sealing is a post-treatment process specially designed for technical precious metal surfaces. The result is a protective, transparent layer just a few nanometers thick. Depending on the application, this layer specifically prevents tarnishing, discoloration and corrosion.
In addition, the product quality is increased by appropriate properties. Umicore Sealing, for example, impresses with a significant reduction in the coefficient of friction, which results in a significant reduction in mating forces for plug contacts.
The technical layer properties, such as the contact resistance, are retained compared to an untreated surface. Subsequent processing (e.g. soldering) is also possible without hesitation.
All our protective coatings do not contain any environmentally harmful components such as solvents, CFCs, CHCs, hydrocarbons or chromium compounds. They are therefore biologically harmless.
