The coating material is prepared by reacting the plurality of polysiloxanes with the cross-linker in the presence of a catalyst. In a preferred embodiment, the unsaturated group of the cross-linker is a vinyl, methacrylate or acrylate group, P.- such as pentaerythitol tetramethacrylate. The coated article may be a fabric.
