A mehod comprising applying a composition to a substrate and curing the composition. This composition is prepared by mixing components including: (I) a polyorganosiloxane having an average of at least two unsaturated organic groups per molecule, with the proviso that component (I) is free of fluorine atoms; optionally (II) an organohydrogenpolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule, with the proviso that component (II) is free of fluorine atoms; (III) a hydrosilylation catalyst; (IV) a fluoroorganosilicone, with the provisos that (1) component (IV) has at least one functional group reactive with component (I), component (II), or both, (2) when component (II) is not present, then component (IV) has an average of at least two silicon-bonded hydrogen atoms per molecule, and (3) component (IV) is added to the composition in an amount sufficient to provide chemical resistance to a cured product of the composition; and (V) an adhesion promoter. |
