TriPass ELV 5500 represents a breakthrough in black trivalent chromium passivation. 

Recommended for both acid zinc and alkaline zinc-iron. It provides excellent corrosion and scratch resistance.

MacDermid TriPass ELV passivation systems comprise the complete range of hexavalent chromium-free products. Available in black, blue and iridescent, the range includes our latest cobalt-free passivates.

Extremely resistant to thermal shock, TriPass ELV passivates form an important layer in the ZinKlad automotive hexavalent chromium-free coatings systems.

Our trivalent passivate TriPass ELV passivation systems meet all ELV Directives through their use of trivalent chromium and pass all automotive industry test requirements, including GM 3034. The perfect drop-in replacement for older hexavalent chromium based chromates, they have all been rigorously tested and used in some of the world’s largest, full scale industrial conditions. They meet the highest specifications from required by both applicators and end users. TriPass ELV passivation systems are the high performance alternatives to hexavalent chromium that not only reduce “white rust” but also deliver exceptional cosmetic appearance.
