Abstract: [Objective]To prepare an acrylic silane ester resin with controllable hydrolysis abilityfor the stable release of antifouling agents within the coating,thereby improving the long-term antifouling performance of self-polishing antifouling coatings.[Methods]Isobornyl acrylate monomerwas introduced into the synthesis route of the conventional acrylic silane ester resin to successfullyprepare a linear hydrolyzable acrylic silane ester resin. The difference in hydrolysis rate between thisresin and the conventional one was compared. A self-polishing antifouling coating was prepared basedon the linear hydrolyzable acrylic silane ester resin and an organic boron antifouling agent. The effect ofresin content variation on the coating’s antifouling performance was investigated.[Results] The polishing rate of the linear hydrolyzable acrylic silane ester resin remained stable at(3±1)μm/month during 6 laboratory test cycles,demonstrating significantly enhanced hydrolysis stability compared to the conventional acrylic silane ester resin. When the content of linear hydrolyzable acrylic silane esterresin in the coating was 32%,the antifouling performance was optimal,along with excellent mechanical properties and coating compatibility.[Conclusion]The linear hydrolyzable acrylic silane ester resineffectively enhances the antifouling performance of self-polishing coatings,enabling long-term foulingprotection for marine facilities such as ships and offshore drilling platforms.
