Anticorrosive Pigments

Heubach initiated the replacement of carcinogenic chrome-based Anticorrosives and became the world market leader in this field. First came standard zinc phosphates, which were free of chrome, but could not match the excellent performance of chromates. That changed, when Heubach introduced modified product lines such as orthophosphates, polyphosphates, organic inhibitors and the WSA-line.

One major breakthrough in the world of Anticorrosives was the discovery of especially one effective organic inhibitor, today well-known under the trade name HEUCORIN^® RZ, which is based on a zinc salt of an organic nitro compound. Adding very small quantities of HEUCORIN^® RZ leads to significant improvements of existing protective coatings and dropped formulation costs.
