Fouling Control Coating Composition

A fouling control coating composition comprising:

• (i) a functional polysiloxane,
• (ii) a functionalised acrylate-based polymer, and
• (iii) a non-curable polymeric or oligomeric fluid that is liquid at 25° C. and atmospheric pressure, where the functional polysiloxane and the functionalised acrylate-based polymer each comprise a silane moiety of formula —Si(Rb)3-a(ORa)a, in which
• each Ra is independently selected from H, and C1-12 alkyl, phenyl, and phenyl with one or more C1-6 alkyl substituents, each Ra group optionally comprising one or more substituents selected from halide, ORt and NRt2
• each Rb is independently selected from H and Rc,
• each Rc is independently selected from C1-20 aliphatic hydrocarbyl groups, C6-12 aryl groups, and C6-12 aryl groups having one or more C1-6 alkyl groups, each Rc optionally comprising one or more substituents selected from from halide, —ORt, —NRt2, —NCO, —C(O)Rt, —C(O)ORt, —OC(O)Rt, —C(O)NRt2, —OC(O)NRt2, —NRtC(O)NRt2, —OC(O)ORt, —([CRt2]jE-)pRt, -E-([CRt2]jE-)pRt and —(CRt2)j[O(CRt2)k]m[CRt(O)CRt2], where [CRt(O)CRt2]represents an epoxy moiety;
• each Rt is independently selected from H, C1-6 alkyl and C1-6 haloalkyl;
• each E is independently selected from —O— and —NRt;
• a is an integer in the range of from 1 to 3;
• j is in the range of from 1 to 6;
• k is in the range of from 2 to 3;
• m is in the range of from 0 to 3;
• and
• p is in the range of from 1 to 20.
