    • The invention relates to a curable dental composition comprising a) a curable organopolysiloxane polymer, b) a crosslinker compound capable of crosslinking said organopolysiloxane polymer, c) a catalyst capable of catalyzing a crosslinking reaction of component (A) and component (B), d) a surfactant, e) a F-containing compound, wherein the F-containing compound has the following formula: (G1-L1-O)s-Rfa-O-L2-G2 wherein: G1 and G2 each independently represents a non-ionic endgroup that is free of polyoxyalkylene groups or contains polyoxyalkylene such that the total amount thereof in the F-containing compound is not more than 10% by weight based on the molecular weight of the F-containing ompound; L1 and L2 each independently represents an aliphatic hydrocarbon group or a partially or fully fluorinated aliphatic hydrocarbon group; Rfa represents a mono-valent or divalent partially or fully fluorinated aliphatic group or a partially or fully fluorinated aliphatic group interrupted by one or more oxygen atoms; with the proviso that at least one of the following conditions is fulfilled: (i) at least one of the moieties L1-G1 and L2-G2 is partially or fully fluorinated or (ii) Rf is a partially or fully fluorinated aliphatic group interrupted by one or more oxygen atoms. The invention also relates to a kit of parts and a method of producing a dental composition as well as the use of the dental composition for the preparation of or as impression material or for the preparation of crowns and bridges.
