Embodiments herein relate to a non-aqueous liquid foul release coating composition for controlling aqueous biofouling on man-made objects comprising a moisture curable polysiloxane comprising repeating units of according to formula (I) as described in the application and at least one terminal or pendant group of according to formula (II) as described in the application; and 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. Embodiments herein further relate to a substrate coated with such coating composition and to processes of use of such coating compositions to control aquatic biofouling of a man-made object.

Foul release coating composition

The present disclosure relates to a tie-coat composition comprising one or more binder polymers obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, wherein the tie-coat composition provides a tie-coat with good dry adhesion, freshwater adhesion and saltwater adhesion to topcoats based on resins with condensable silane groups such as polydiorganosiloxane resins with hydrolysable groups or organic resins with terminal and/or pendant alkoxysilyl groups. The present disclosure further relates to a process for controlling aquatic fouling on a surface of a man-made object comprising applying such tie-coat composition and a topcoat composition, and to a substrate coated with a tie-coat layer deposited from such tie-coat composition and a topcoat layer.
