    摘要: A curable fluorosilicone composition of the present invention comprises: (A) an organopolysiloxane having at least two alkenyl groups and at least one fluoroalkyl group in a molecule; (B) an organopolysiloxane having at least two silicon atom-bonded hydrogen atoms and at least one fluoroalkyl group in a molecule; (C) a platinum group metal-based catalyst for hydrosilylation reaction; and (D) a hydrosilylation reaction inhibitor having an aliphatic unsaturated bond; wherein component (C) is an encapsulation type catalyst having an acrylic resin as a wall material, and the platinum group metals in component (C) relative to the present composition are 0.1 to 100 ppm, and the molar ratio of the aliphatic unsaturated bonds in component (D) relative to the platinum group metals in component (C) is 1 to 100. The composition is charcterized by having favorable curability and a sufficiently pot life at room temperature.
