<p>A curable composition comprising: (A) a branched polyfluorodialkenyl compound represented by a general formula (1): CH2=CH-(X)a-Rf<1>-(X')a-CH=CH2 wherein, X and X' are bivalent groups such as -CH2- and -CH2O-, a represents, independently, either 0 or 1, and Rf<1> is a specific bivalent fluorine-containing group, (B) a branched polyfluoromonoalkenyl compound represented by a general formula (2): Rf<2>-(X')a-CH=CH2 wherein, X' and a are as defined above, and Rf<2> is a specific fluorine-containing group, (C) an organohydrogensiloxane compound with at least two hydrogen atoms bonded to silicon atoms, and (D) a platinum group metal catalyst; as well as a low bleeding gel type cured product obtained by curing such a composition, and an electrical or electronic component sealed or encapsulated using such a cured product. The gel type cured product displays very little bleeding of free oil constituents from the gel as a result of stress such as pressure fluctuation or heat history.</p> |
