Passivation processes are used to provide high corrosion resistance. Technic passivation chemistry, including solutions for alkaline, acid zinc and zinc alloys, is available in a variety of colors according to the level of corrosion resistance required.
Cobalt-free and cyanide-free options are also available.
Cobalt salts like cobalt nitrate, cobalt sulphate and cobalt carbonate have been included in the SVHC list under the REACH regulation, prompting users to explore alternatives in the event of a future prohibition of use.
Technic supply an expanding range of high performing cobalt-free passivations for alkaline, acid zinc and zinc alloys in a variety of colors, depending on the level of corrosion resistance required.
Trivalent chrome blue conversion coating for alkaline or acid zinc, with or without cyanide. Excellent corrosion and temperature resistance.
Trivalent chrome black conversion coating with high corrosion resistance for alkaline zinc. No white rust for over 90 hours.
Black trivalent chrome conversion coating for alkaline zinc. No white rust for 120-168 hours or longer.
Technic's selection of industrial post treatment chemistry also includes anti-tarnish chemistry, coatings, and metal strippers. Additionally, Technic offers industrial Pretreatment Chemistry, Electrolytic Plating Chemistry, Electroless Plating Chemistry, and Immersion Chemistry.
