The self-polishing copolymer (SPC)s release biocides by the mechanism of a hydrolysis or ion exchange reaction of an acrylic polymer with seawater. So it has been variously applied to antifouling paints as the binder. The poly(ethylene oxide) (PEO) has been used as a drag-reduction(DR) addictive in aqueous systems, there were researches of proving the DR effect of that . We have confirmed the DR effect of PEO applied to the SPCs mechanism at the surface of a panel and whether the leaching rate of PEO in SPCs is constant or not. In this study we made test panels employing SPCs paint (tin-free, copper-free) containing PEO. Then we checked the surface roughness and condition of panels depending on the discharge of PEO. In addition, the properties of samples are studied through the immersion, leaching rate and Drag-reduction tests. The experiments have been investigated the correlations between the leaching rate, DR effect and the content of the PEO.
