The development of new green alternatives for anticorrosive and antifouling coatings is essential for the conservation of the environment. A coating with more than one functionality, for example both anticorrosion and antifouling is of great interest for cost reduction and for improved coating efficiency. In a new work, the multifunctional effect of propolis within a silicone matrix coating was evaluated. Electrochemical impedance spectroscopy (EIS) experiments showed that the presence of propolis increased the anticorrosive properties, and bacterial experiments showed decreased adhesion of the gram-positive bacteria Staphylococcus aureus (ATCC 6538). Marine experiments also showed the excellent antifouling efficiency of the paint ...
