Resumen:
tIt is well known that during the first minutes of the immersion of any substrate in marine environmentsmicrobial colonization takes place. This event will condition the attachment of other more complexorganisms and the substrate biodeterioration with concomitant loss of its functionality. The aim of thiswork was to assess antifouling coatings performance at early stages of immersion, in natural and artificialsea water, observing the surface condition, by scanning electron microscope (SEM), in order to predictpossible results in long time immersion tests. The use of short time tests to predict future behavior isuseful to adjust formulations, reduce testing time and economics cost.In this research antifouling (AF) coatings formulated with two ?quebracho? tannin derivatives werechosen to be evaluated by short and long time tests. One of this coatings possessed in a longer servicelife, until 10 months of exposure, and at the same time, this resulted correlated with surface analysis atearly stages of immersion by SEM.
