Descripción
Steel panels must be protected during storage and transportation because they can corrode.This protection used to be afforded by chromate primers, but now a days tannin-based primers are being studied.These primers are not only used as protection but also as adhesion promoter if the steel surfacewas not well prepared (presence of oxides or low roughness). The objective of this work was to prepare lanthanum“tannate”,employing tara and quebracho tannins. The “tannates”were incorporated in primers formulation and applied on steel SAE1010 panels (previously exposed to the humidity chamber or with 6μm of roughness depth). These primed panels were exposed to humidity chamber where corrosion and blistering degrees were evaluated. Adhesion test were done. Electrochemical assays such as ionic resistance and corrosion potential measurements were carried out. Results showed that the adhesion and the barrier properties of the primers were good. Besides, on low roughness steel, the primers diminished the corrosion current. Results were compared with traditional zinc tetroxy chromate primer.
