Resumen:
A B S T R A C T Biofouling leads to deterioration of any submerged material. The most widespread method for control is the application of cuprous oxide antifouling paints which are toxic. For this reason non-toxic natural products could be combined with small amounts of copper to diminish its contribution to the environment. The aim of this work was to reduce the amount of copper in antifouling paints employing thymol as an additive. Two antifouling paints were prepared, one containing 16% v/v copper and another with 1.6% copper + 2% thymol. After 6 months of immersion in Mar del Plata harbour paints containing 1.6% copper + thymol and 16% copper were effective. Although these formulations showed a similar performance, copper+thymol based paint contains 90% lesser copper than a traditional copper based formulation. Then, the aim of this work was reached.
