A blue antifouling paint consisting of 9% by weight of n-butyl acetate and 25% by weight of xylene was applied twice to the test steel/plate and kept immersed in the sea at a depth of 1.5m in Tsukumi Bay in the Oita system for 1 year. When we investigated the adhesion status of fouling organisms to the steel plate, we found that after 6 months of immersion, the adhesion area percentage of fouling organisms was 0%, and after 12 months it was 5%, indicating that the excellent antifouling effect lasted for a long time. I found out that it works well.
