Traditional antifouling coatings include paint layers: anti-corrosion primer, intermediate paint and antifouling paint. To overcome the difficulty of bonding between paint layers, a coating that integrates antifouling and anti-corrosion capabilities in the same coating on an ethyl silicate binder has been researched. In the pigment mixture including spherical Zn, flake ZnAl and Cu2O, the effect of spherical Zn content (30 wt%, 40 wt% and 50 wt%) on anti-corrosion properties was investigated by electrochemical impedance spectroscopy and polarization curves. The results after 30 days of soaking in 3.5 wt% NaCl showed that the total resistance of the coatings increased, and the corrosion resistance of the coating with 50 wt% Zn content reached the highest efficiency, the impedance module reaches the value 50,2 kΩ.cm2. The polarization curve method also confirmed the corrosion protection of the integrated coatings following a cathodic protection mechanism. Antifouling test results in natural seawater environment after 2 months of testing showed that, with appropriate Zn content (30 wt% Zn), an integrated coating with the lowest fouling density was created in the research samples, the coating surface only shows a biofouling film, the surface is still visible under the fouling layer%. Test results show that the integrated coating has the ability to prevent settlement and inhibit the growth of marine microorganisms for 2 months.
