A composition for a solvent resistant silicone gel which comprises (A) 100 weight parts of branched organopolysiloxane having vinyl groups which contains: -(CF3-CH2-CH2)(CH3)SiO units 70.0-98.5 mol % -RSiO1.5 units 0.5-10.0 mol %, and -(CH2=CH)(CH3)2SiO0.5 units 1.0-10.0 mol %, - where R is a group selected from a 3,3,3-trifluoropropyl group, a phenyl group, a methyl group and a vinyl group, (B) 0.1 to 30 weight parts of organohydrogen polysiloxane having at least one hydrogen atom bound to a silicon atom within the molecule, and (C) an addition reaction catalyst. The composition can form a cured silicone gel product which possesses a superior solvent resistance towards, for example, gasoline, while maintaining flexibility at low temperature.
