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
"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.
