Abstract:
1. A curable dental composition comprising: an addition curable silicone component (A) represented by formula (3): wherein: R1=alkyl, aryl or alkaryl each comprising 1 to 20 carbon atoms, wherein at least one of the carbon atoms can be substituted with a halogen atom or alkyl group; R2=equal to R1; R3=alkyl, aryl or alkaryl group comprising 1 to 20 carbon atoms, wherein one or more of the H atoms can be substituted by a halogen atom; R4=linear or branched, terminally unsaturated aliphatic, cycloaliphatic or aromatic organic or silicon organic residue moiety having (a−1) ethylenic unsaturations, and wherein such unsaturations are carbon-carbon double bonds not activated by a conjugated carbonyl group, wherein the moiety comprises 1 to 50 carbon atoms and additionally up to 6 oxygen atoms which can also be part of a ring system; a=4, 5, 6, 7, 8, 9 or 10; o=0 to 12; m=0 to 50; and p=1 to 500; a crosslinker component (B) comprising at least 2 SiH groups; a catalyst component (C); and a filler component (D), wherein the total number of carbon-carbon double bonds in component (A) is at least 3, and R4 does not comprise a vinyl group that is directly attached to a silicon atom; and further wherein the composition, after curing, has a shore hardness D above about 35 and up to about 95, and is used as a dental material.
