SILICATE-ZINC ANTIFOULING PAINTS. STUDIES ON ANTIFOULING PROPERTIES

Abstract

Accelerated and land tests proved that the action of preservative coatings consisting of silicate paints depends on the content of oxides of copper in the paint making up the external layer of the coating. The content of Cu2O is increased, the anticorrosion properties decrease and antifouling properties become better. Coatings with 21.1% Cu2O have good anticorrosion properties but insufficient antifouling properties, primarily as concerns barnacles. The addition of zinc oxide (21% Cu2O and 33.5% Zn at the optimum) improves antifouling without harming anticorrosion properties.
