Abstract

The invention relates to a non-aqueous liquid foul release coating composition for controlling aqueous biofouling on man-made objects comprising i) a moisture curable polysiloxane comprising repeating units of formula (I) and at least one terminal or pendant group of formula (II) and ii) at least one of a marine biocide or a non-volatile component comprising units selected from hydrocarbyl, heterocarbyl, halocarbyl, ether, ester, amide, ketone, siloxane, urethane or urea groups. The invention further relates to a substrate coated with such coating composition and to use of such coating composition to control aquatic biofouling of a man-made object.
