Abstract

The present invention relates to a substrate coated with a multi-layer coating system comprising: a) optionally a primer layer applied to the substrate and deposited from a primer coating composition; b) a tie-coat layer applied to the substrate or to the optional primer layer, deposited from a tie-coat composition comprising a binder polymer obtainable by copolymerizing a mixture of ethylenically unsaturated monomers, the binder polymer comprising curable alkoxysilyl functional groups; and c) a topcoat layer applied to the tie-coat layer, the topcoat layer deposited from a non-aqueous liquid foul release coating composition comprising a curable resin system comprising i) a curable polymer having a backbone selected from a polyurethane, a polyether, a polyester, a polycarbonate or a hybrid of two or more thereof, and having at least one terminal or pendant alkoxysilyl group, andoptionally, ii) a curing agent and/or a catalyst, wherein the non-aqueous liquid foul release coating composition is essentially free of a curable polysiloxane. The invention further relates to a process for controlling aquatic biofouling on a surface of a man-made object.
