In a previous work, the purification and the characterization of condensed   tannins extracted from the heartwood of quebracho (Schinopsis sp.) were        performed particularly with the objective of knowing some inherent properties to the reaction between the tannins and the iron oxides. In the present work, several water-based pretreatments with condensed tannic acids and solvent-based anticorrosive coatings with metallic tannates were formulated and manufactured. Coating       systems performance was assessed in laboratory tests.
