Assessment of tannin antifouling coatings by scanning electron microscopy

In this research antifouling (AF) coatings formulated with two “quebracho” tannin derivatives were chosen to be evaluated by short and long time tests. One of this coatings possessed in a longer service life, until 10 months of exposure, and at the same time, this resulted correlated with surface analysis at early stages of immersion by SEM.
