ABSTRACT:
The present invention provides a sealing component for connector waterproofing having an excellent heat resistance, low-temperature resistance and oil resistance which can be economically produced in a reduced molding time. A novel sealing component for connector waterproofing is provided, which comprises a vulcanized composition comprising at least (a) 100 parts by weight of an organopolysiloxane represented by the following average composition formula (I) containing at least two alkenyl groups per molecule and having a viscosity of at least 100,000 cs, (b) from 0.1 to 20 parts by weight of an organohydrogenpolysiloxane represented by the following average composition formula (II) containing at least two hydrogen atoms directly bonded to silicon atom per molecule, (c) from 5 to 500 parts by weight of a finely divided silica filler, (d) the catalytic amount of a platinum catalyst, (e) from 0.005 to 5 parts by weight of a sulfide compound represented by the following general formula (III), and (f) from 0.005 to 5 parts by weight of a triazine compound represented by the following general formula (IV), the formulas (I), (II), (III) and (IV) being as described herein.
