Dental silicone impression material composition

A dental silicone impression material composition comprising:

• A) 100 weight parts of an organopolysiloxane mixture comprising a) an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule and having viscosity of 1,000,000 mPa·s or more at 25° C., and b) an organopolysiloxane having at least one aliphatic unsaturated hydrocarbon in one molecule and having viscosity of 100 to 5,000 mPa·s at 25° C., wherein a ratio of a):b) is 1:0.5 to 10;
• B) 0.1 to 100 weight parts of an organohydrogenpolysiloxane having at least three hydrogen atoms directly bonded to a silicon atom in one molecule with respect to 100 weight parts of the component A);
• C) 10 ppm to 1 weight part of a silicone-soluble platinum compound with respect to the total amount of the two components A) and B);
• D) 1 to 50 parts of an organopolysiloxane not having a functional group with respect to 100 weight parts of the component A);
• and
• E) 10 to 100 weight parts of an inorganic filler with respect to 100 weight parts of the component A).
