| Résumé : |
The efficiency of coating systems in the protection of metallic substrates depends fundamentally, in relation with formulation variables, on the type and content of corrosion-inhibitive pigment, the characteristics of the film forming material and the pigment/binder ratio. In this study, chromium (VI) tannates with several metal contents in their composition were used as inhibitive pigments in anticorrosive paints. The mentioned metallic tannates were prepared at laboratory scale under controlled operative conditions. Some properties of chromium tannates as well as the protective efficiency of anticorrosive paints formulated with the quoted inhibitors were assessed in laboratory tests. |
