A composition and its use as a mold release composition are disclosed. The composition comprises a fluorotelomer, which comprises repeat units derived from a fluoroalkene, and optionally a comonomer, and has an endgroup derived from an alcohol, an alcohol derivative, or a combination thereof, and said fluorotelomer has or comprises a structure depicted as H(CX2)pBqDr or a mixture of structures depicted as H(CX2)pBq and H(CX2)pDr, wherein each X is independently H or F, provided at least one X is F, p is a number from about 16 to about 1500, B represents a unit derived from a hydrofluorocarbon, q is a number from 0.02 to 0.4, D represents an endgroup derived from said alcohol, alcohol derivative, or combination thereof, and r is a number 0.2 to 1.0. The composition comprises a silane having the formula R1n—Si-(Z)4-n wherein Z is OR2, Cl, or H, wherein R1 is selected from the group consisting of hydrogen, a hydrocarbon radical having 1-34 carbon atoms, and combinations of two or more thereof, R2 is selected from the group consisting hydrogen, a hydrocarbon radical having 1-4 carbon atoms, and combinations of two or more thereof, provided that R1 and R2 both cannot be hydrogen, and n is a number from 1 to 3. The composition may further comprise a solvent and/or a catalyst.
