BASF and voestalpine have developed a steel passivation compound that is free of heavy metals

Chromium-free and fluoride-free passivating compound for use in conversion coatings applied to galvanized steel strip

05-Apr-2007

For the first time, BASF will be presenting a pioneering passivating compound that is free of chromium and fluoride for use on galvanized steel strip at the 2007 Hanover Fair. This innovative BASF product has been developed in cooperation with voestalpine Stahl GmbH. BASF's Lugalvan® passivating compound has performed successfully in trials in voestalpine's production facilities and in other European and American steelworks.

"We were looking for a non-toxic compound that was free of heavy metals and that could be used in conversion coatings and decided to combine our expertise in steel with BASF's chemistry know-how to develop this chromium- and fluoride-free alternative," said Martin Fleischanderl, head of the project at the Austrian steelmaker voestalpine.

The new Lugalvan passivating compound is completely organic and has been tested in extensive production trials.
