Abstract:
A silicone composition useful for dental temporary sealing, which comprises:(A) 100 parts by weight of an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule and having a viscosity of from 50 to 1,000 cSt at 25.degree. C.;(B) from 0.1 to 40 parts by weight of an organohydrogenpolysiloxane having at least three hydrogen atoms directly bonded to a silicon atom in one molecule;(C) from 10 to 500 ppm, based on the total amount of (A) and (B), of a silicone-soluble platinum compound;(D) from 10 to 400 parts by weight of an inorganic filler selected from the group consisting of quartz, cristobalite, diatomaceous earch, fused quartz, titanium dioxide and fused silica; and(E) from 5 to 50 parts by weight, based on the amount of (A) of powdered silica having a BET specific surface area of from 50 to 500 m.sup.2 /g, the surface of which is hindered by a hydrophobic group selected from the group consisting of (CH.sub.3).sub.3 SiO.sub.1/2 unit, (CH.sub.3).sub.2 SiO.sub.2/2 unit and (CH.sub.3)SiO.sub.3/2 unit.
