摘要（英）：

The invention provides an antifouling system comprising silicone hydrogel. 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): (R1O)a(R1)(3-a)Si-R2-(Si(R1)2O)p-Si(R1)2-R2-O-(CH2-CHR1-O)q-R1 (1) where a is 1-3; R1 is H or alkyl radical from C1 - C10; R2 is alkylene from C2-C10; p is 1- 100; and q is 1-50. The base coating composition can comprise an epoxy modified adhesion promoter. Additionally, the antifouling coating composition can comprise an acetoxy, alkoxy, and/or ketoxime functional adhesion promoter.
