Curable coating compositions made from a fluorosilicone polymer of the formula. YMeSiO (MeSiO) (RQ) MeSiO] y (MeViSiO) SiMeY ,. the Y represents an alkenyl group or a vinyl group and RQ represents a silicon-bonded fluorinated radical; an organohydrogenpolysiloxane crosslinking compound represented by the formula. Me.SiO (MeHSiO) [(RQ) MeSiO] SiMe ,, where the sum of m. 3 ni n 3. and n is between 20 and 80 and where RQ represents a silicon-bonded fluorinated radical; a catalytic amount of metal-containing hydrosilation catalyst; and an effective amount of inhibitor for the catalyst. This composition, after curing, provides a protective, release liner, especially for silicone pressure sensitive adhesives, with shorter curing time and longer service life than other known compositions. |
