摘要：
Curable coating compositions for preventing biofouling include a) at least one epoxy resin; b) at least one amine-functional poly(dialkylsiloxane) polymer in an amount from 1 to 70% based on the combined weights of components a) and b); and c) at least one alkylene polyamine, polyalkylene polyamine or polymercaptan epoxy curing agent; wherein components b) and c) together provide about 0.75 to 1.5 equivalents of amine nitrogen atoms and/or thiol groups per equivalent of epoxy groups provided by component a). When cured to form an antifouling coating, the coating exhibits a water contact angle of at least 100° as measured using an optical contact angle meter at 22°C. The coating composition adheres well to many substrates, provides good anticorrosion protection and is an effective anti-biofouling measure.
