Abstract
Seven compositions of anticorrosion pigments of zinc-strontium borophosphat es were prepared and then characterized by X-ray diffraction analysis, solu bility measurements, particle size distribution, and the pH of their aqueou s extracts. The Figments were dispersed in an alkyd resin formulation, and used in paints. Following application of the paints to steel sheets, they w ere subjected to standard anticorrosion tests, to assess their anticorrosiv e-inhibitory properties. Test results showed that 14.6SrO-43.7ZnO-8.3B(2)O( 3)-33.3P(2)O(5) and 37.5SrO-37.5ZnO-25B(2)O(3) compositions surpassed the a nticorrosive properties of standard pigments based on zinc orthophosphate a nd calcium metaborate.
