The invention relates to a composition comprising a prepolymer as component (A), wherein the prepolymer comprises aziridino groups and is characterized by an equivalent weight EW1, a crosslinker as component (B), wherein the crosslinker has a structure being different from the structure of the prepolymer and comprises aziridino groups and is characterized by an equivalent weight EW2, an initiator as component (C) being able to start curing of the composition, optionally filler(s) as component (D) and optionally additive(s) as component (E), wherein equivalent weight is defined as (molecular mass of the molecule) / (number of aziridino groups present in the molecule) and wherein EW1 > EW2.
The invention also relates to the use of the composition for coating, sealing, moulding, adhering, making impressions, producing a dental material.
本发明涉及一种组合物,该组合物包括作为组分(A)的预聚物,其中预聚物包含氮丙啶基团,其特征在于等效重量 EW1;作为组分(B)的交联剂,其中交联剂的结构与预聚物的结构不同,包含氮丙啶基团,其特征在于等效重量 EW2、作为成分(C)的引发剂能够启动组合物的固化,作为成分(D)的可选填料和作为成分(E)的可选添加剂,其中等效重量定义为(分子的分子质量)/(分子中存在的氮丙啶基数),其中 EW1 > EW2。
本发明还涉及将该组合物用于涂层、密封、成型、粘合、制模、生产牙科材料。
