Patent ID: 7045586

Claim:
A composition prepared by mixing components comprising: (I) a polyorganosiloxane having an average of at least two unsaturated organic groups per molecule, where component (I) is free of fluorine atoms; (II) an organohydrogenpolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule, where component (II) is free of fluorine atoms; (III) a hydrosilylation catalyst; (IV) a fluoroorganosilicone having at least one functional group reactive with component (I), component (II), or both; (V) an unsaturated ester-functional compound comprising v) a combination thereof; where in formula i), each R 18 is independently a hydrogen atom, a monovalent hydrocarbon group of 1 to 4 carbon atoms, or CF 3 , each R 19 is independently a divalent organic group of 1 to 20 carbon atoms, each R 20 is independently a hydrogen atom or a monovalent hydrocarbon group of 1 to 20 carbon atoms, in formula ii), n has an average value of 0 to 2 and m =4−n, each R 21 is independently a hydroxyl group, or CF 3 . each R 22 is independently a hydrogen atom, a monovalent hydrocarbon group of 1 to 4 carbon atoms, or CF 3 , each R 23 is independently a hydrogen atom or a monovalent hydrocarbon group of 1 to 20 carbon atoms, in formula iii), each R 24 is independently a fluoroalkyl group, an epoxy functional group, or a polyether group with the proviso that at least one of R 24 or R 25 is unsaturated, each R 25 is independently an oxygen-bridged monovalent organic group or a carbon-bridged carbonyl group, in formula iv), each R 26 is independently a monovalent organic group or a hydrogen atom, with the proviso that at least one R 26 is an aliphatically unsaturated monovalent organic group or a hydrogen atom, and each R 27 is independently an oxygen atom or a divalent organic group; and (VI) an adhesion promoter.
