Abstract
A copolymer composition is provided that is formed as the reaction product of (I) a cured polyorganosiloxane intermediate having repeating Si—O—Si units and at least one Si—OH functional group and (II) a polyfluoropolyether silane. The cured polyorganosiloxane intermediate has a surface having a water contact angle ranging from 40° to 90° as measured by ASTM 5946-04. In certain embodiments, the copolymer composition provides improved dust resistance as compared with cured polyorganosiloxanes from which the copolymer composition is formed.
