dc.description.abstractThe aim of this research was to evaluate the anticorrosive properties of alkyd paints and wash primers formulated with zinc tannates containing Tara tannins. Their inhibitory efficiency was compared with paints pigmented with well-known anticorrosive pigments by accelerated corrosion tests (salt spray test, Prohesion test, and sulphur dioxide test), natural exposure tests and some electrochemical techniques (corrosion potential, polarization resistance and impedance measurements). It was demonstrated that the capacity of inhibiting corrosion of zinc tannates is equivalent to that shown by most commercially available conventional pigments, such as zinc phosphate and zinc chromate.
dc.description.sponsorshipFunding: This research was supported by FINCyT (Fondo para la Innovación, la Ciencia y la Tecnología) , [grant No 158-FINCyT-IA-2013 ], and agreement PUCP (Pontificia Universidad Católica del Perú) – FONDECYT (Fondo Nacional de Desarrollo Científico y Tecnológico) [grant No 012-2013 ]. The authors would particularly like to thank PUCP Chemistry Section for the FTIR analysis, PUCP Material Characterization Centre for the SEM-EDS analysis, and the UNIVERSAL COLORS Company for the supply of materials and commercial coatings, and for the painted service. We also thank to Dr. Pablo Aguilar, Professor at the National University of Trujillo (Peru), for providing information about the environmental conditions of Chimbote research station.
