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. The new balance between performance and cost provided HEUCORIN® RZ with the missing access to mainstream applications. As a result more and more formulators use HEUCORIN® RZ to optimize the protective properties of their anticorrosive coatings. HEUCORIN RZ does and certainly will play a key role in protective coatings of the future.
