silver protect passivation

Arega® protect 200

Invisible deposits of high effectiveness

Arega® protect 200 is an aqueous passivation bath, free of metals which deposits transparent, colourless protective coatings on silver and gold-copper-alloy surfaces.
The protective system is based on a molecular nanobiotechnology. The molecules adsorb on the surface and cross link by forming a few nanometers thick protective layer.
The produced layer protects the surfaces from tarnishing, so discolouration can be prevented for longer period of time. Through passivation conductivity and soldering are only insignificant reduced.
