    摘要： The invention provides a method to reduce evolution of hydrogen gas especially during pouring gypsum models from addition cured silicones. In this respect the invention relates to an addition curable silicone composition, comprising an addition-curable siloxane compound, a siloxane crosslinker, a catalyst and an unsaturated silane compound with at least one methylene group directly attached to the unsaturation in an amount effective to reduce the amount of hydrogen gas evolved in the reaction of said composition.

    摘要： 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 compound; 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.
