Abstract
Disclosed in a mold release composition comprising a fluorosilicone compound of the formula (I): (I) wherein R1, R2, R4, R5, R6, R7, R8 and R9 each is, the same or different, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group, R3 and R10 each is; the same or different, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group, or Rf—X—, or Z—Y— in which X and Y each is; the same or different, a divalent organic group, Rf is a C1-6 fluoroalkyl group, Z is a silyl group containing a hydrolyzable site, m is 1-100, n is 1-50, and o is 0-200. The mold release composition can give excellent mold releasability and durability of mold releasability (repeated mold releasability).
