摘要：
A liquid curable fluorosilicone composition having improved defoamability is provided. The composition comprises
(A) an organopolysiloxane having a viscosity at 25°C of 100 to 500,000 mPa·s and represented by the following formula:
(CF 3 CH 2 CH 2 ) a R b SiO (4-a-b)/2
wherein R is a monovalent hydrocarbon group with the proviso that at least 0.001% by mole of the hydrocarbon group is an alkenyl group, a is 0.1 to 1.0, b is 2.5 to 1.0, and a+b is 1.8 to 3.0,
(B) an organohydrogenpolysiloxane containing at least two hydrogen atoms bonded to the silicon atom in a molecule,
(C) an addition catalyst, and
(D) a diorganopolysiloxane having a viscosity at 25°C of 1 to 10,000 mpa·s which does not comprise trifluoropropyl group but comprises dimethylsiloxane unit.
