    • 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.
    • 本发明涉及一种可固化牙科用组合物,其包含a)可固化的有机基聚硅氧烷聚合物,b)能够交联所述有机聚硅氧烷聚合物的交联剂化合物,c)能够催化组分(A)和组分(B)的交联反应的催化剂,d )表面活性剂,e)含F化合物,其中所述含F化合物具有下式:(G1-L1-O)s-Rfa-O-L2-G2其中:G1和G2各自独立地表示非 - 不含聚氧化烯基团或含有聚氧化烯的离子性端基,使得其含氟化合物的总量相对于含F化合物的分子量为10重量%以下; L1和L2各自独立地表示脂族烃基或部分或完全氟化的脂族烃基; Rfa表示被一个或多个氧原子间隔的一价或二价部分或完全氟化的脂族基团或部分或全部氟化脂族基团; 条件是满足以下条件中的至少一个:(i)部分L1-G1和L2-G2中的至少一个部分或完全氟化,或(ii)Rf是部分或完全氟化的脂族基团,被 一个或多个氧原子。 本发明还涉及一种用于制备牙科用组合物的试剂盒和牙科用组合物的制备方法,或用作制备印模材料或用于制备牙冠和牙桥的牙科用组合物。
