New study of anticorrosive efficiency of core-shell pigments
Article Type: New materials and equipment From: Anti-Corrosion Methods and Materials, Volume 56, Issue 2
Andrea Kalendova and David Vesely, University of Pardubice, Czech Republic published recently a study of the anticorrosive efficiency of zincite and periclase-based coreshell pigments in organic coatings. The objective of this work was to identify the anticorrosive efficiency of synthesized, MeO/core pigments and of MeO pigments (MeO=ZnO, MgO) with varied morphology of particles. The synthesized MeO-type pigments displayed varied particle morphologies and the MeO/core coreshell pigments exhibited surface of particles made of zincite and periclase. These coreshell pigments have the properties of both the ZnO layer and of the core (wollastonite or graphite). Epoxy-ester based coatings containing the synthesized pigments were also formulated. To test the anticorrosion properties of the coatings, accelerated corrosion tests were carried out in the environment of condensed water, of NaCl mist, and of condensing water and SO2. The synthesized coreshell pigments have good anticorrosion efficiency in an epoxy-ester coating. Progress in Organic Coatings, Volume 64, Issue 1, pp. 5-19.
