[ES] Se formularon unas pinturas de vinil/acrilato y TBT acrilato/MMA/BMA que contenían tóxicos para la protección contra las incrustaciones biológicas de probetas sumergidas en el mar. Como tóxicos se dispersaron en la solución Cu2O, Irgarol 1051 (Ciba), Preventol A4S (Bayer) y Lolo tint Cu2O (American Chemet). Estas pinturas se ensayaron en una balsa fondeada en el puerto de Palma de Mallorca. Un número reducido de probetas se sumergieron en condiciones adecuadas en tanques con agua de mar, que circulaba constantemente y se hizo la determinación de la Iixiviación de Cu para medir la efectividad de la pintura durante un año. La información combinada de los ensayos biológicos y de Iixiviación fue satisfactoria para comprobar la calidad de las pinturas. En el trabajo se discuten las ventajas e Inconvenientes de las diferentes formulaciones.
[EN] Vlnyl/TBT acrylate and TBT acrylate/(MMA/BMA) based paints containing biocides have been developed for the protection of underwater surfaces from fouling growth. Suitable biocides Cu2O, Irgarol 1051 (Ciba), Preventol A4S (Bayer) and Lolo tint Cu2O (American Chemet) have been used Paints have been tested In a raft placed In Palma de Mallorca. Copper leaching rate test in the laboratory have been performed, during one year, for some of the above mentioned formulations. Panels have been inmersed in the laboratory under controlled conditions. The combined Information of the biological and copper leaching rate tests has been suitable for testing the quality of the paints. The advantages and disadvantages of different paints formulations are discussed.
