Se ha realizado la optimización de una serie de composiciones de pinturas anticorrosivas, ensayadas con anterioridad en balsas experimentales como etapa previa a la iniciación de experiencias sobre carenas de embarcaciones. En las formulaciones se emplean cinco pigmentos anticorrosivos (minio, silicocromato básico de plomo, sulfato de plomo-aluminio y cromatos básicos de cinc de diferente solubilidad). Los mismos fueron dispersados en un barniz de resina fenólica-aceite de tung, al cual se incorporaron diferentes proporciones de caucho clorado de 20 cP. Sistemas de pinturas aplicados sobre paneles con diferente tratamiento de superficie, fueron ensayados en línea de flotación y en carena en la balsa de Puerto Belgrano.

The optimizing of a series of anticorrosion paints tested previously in experimental rafts has been done. This is a new approach to this subject, before the application of that paints on ship bottoms. Five anticorrosion pigments (lead oxide, basic lead silicochromate, basic lead sulfate-aluminium and two basic zinc chromates of different solubilities) were used in the formulations. The pigments and extenders were dispersed in a binder based in a phenolic varnish where different quantities of chlorinated rubber (20 cP) had been incorporated. The paint systems were applied on plates with different surface treatment and tested in the experimental raft at Puerto Belgrano.
