摘要: An oil-bleeding waterproof sealer for a connector comprising a vulcanized and molded article of a composition comprising: (A) 100 parts by weight of a diorganopolysiloxane green rubber containing at least two alkenyl groups bonded to silicon atoms per molecule thereof, (B) from 10 to 100 parts by weight of a reinforcing filler, (C) from 0.1 to 10 parts by weight of an organohydrogenopolysiloxane having at least two hydrogen atoms bonded to silicon atoms per molecule thereof, (D) from 1 to 30 parts by weight of a phenyl-containing diorganopolysiloxane having a viscosity of 1 to 3,000 cSt at 25.degree. C., and (E) a catalytic amount of a catalyst for hydrosilylation having a particle size of 0.01 to 20 .mu.m, which comprises a platinum catalyst and a non-silicone series thermoplastic resin having a glass transition point of 50.degree. to 200.degree. C., with the proportion of metallic platinum in the catalyst for hydrosilylation being 0.01 to 5% by weight.
