1. A coating composition formed from components comprising:

  • (a) at least one polysiloxane comprising at least one reactive functional group, the polysiloxane comprising at least one of the following structural units (I);

    R1nR2mSiO(4-n-m)/2



    (I) wherein each R1, which may be identical or different, represents H, OH, a monovalent hydrocarbon group or a monovalent siloxane group;

    each R2, which may be identical or different, represents a group comprising at least one reactive functional group, wherein m and n fulfill the requirements of 0<

    n<
