Abstract

A transport mechanism of anticorrosive pigment species (i.e. chromates) in polymer films was investigated. This mechanism plays a crucial role in the performance of anticorrosive polymer coatings which relays on leaching of active anticorrosive species from sparingly soluble pigment particles distributed in the coating. Except for anticorrosive pigments other particles are included in coatings such as pigments with different functions or fillers.The goal of this work was to investigate how filler particles with no anticorrosive function (i.e. BaSO4) could be involved in formation of the pathways for chromate ion transport . Polymer films containing BaSO4 particles with different pigment volume concentration (PVC) were exposed to chromate solution allowing migration of chromate species.
