Abstract

A multi-layer or single layer antifouling coating system. A multi-layer coating system comprises (a) a base coating for coating a substrate, and (b) an antifouling coating composition adapted to be disposed over the base coating, the antifouling coating composition comprising a functionalized polymer, and a curable polyether-containing silane of the Formula (1): (RO)(R)Si—R—(Si(R)O)—Si(R)—R—O—(CH—CHR—O)—R(1) where a is 1-3; Ris H or alkyl radical from C-C; R2 is alkylene from C-C; p is 1-100; and q is 1-50. The base coating composition can comprise an epoxy modified adhesion promoter. Additionally, the anti-fouling coating composition can comprise an acetoxy, alkoxy, and/or ketoxime functional adhesion promoter.
