The present disclosure relates to a curable composition to be prepared by mixing a base paste and a catalyst paste, the base paste comprising (A) a hardenable compound comprising at least two aziridine moieties, and (B) a metal containing component containing anions and/or ligands, the metal containing component being present in an amount of about 0.1 to about 5 wt.-%, the metal being selected from Zn, Cu, Co, Ni, Ag and combinations thereof, the anions or ligands being selected from oxide, hydroxyl, (hydro)carbonate, sulphate, nitrate, halide, lactate, benzoate, wolframate, linear or branched aliphatic carboxylic acid anions, ligands having not more than two coordinating moieties and combinations thereof, the catalyst paste comprising (C) a Lewis acid, the composition optionally further comprising (D) a retarder, (E) filler and (F) additive(s). 1. A curable composition to be prepared by mixing a base paste and a catalyst paste , wherein the base paste comprises(A) a hardenable compound comprising at least two aziridine moieties, and the metal containing component being present in an amount of about 0.1 to about 10 wt.-% with respect to the weight of the base paste,', 'the metal being selected from Zn, Cu, Co, Ni, Ag and combinations thereof,', 'the anions or ligands being selected from oxide, hydroxyl, (hydrogen)carbonate, (hydrogen)sulphate, (hydrogen)phosphate, sulphate, halide, lactate, benzoate, wolframate, linear or branched aliphatic carboxylic acid anions, ligands having not more than two coordinating moieties and combinations thereof,, '(B) a metal containing component containing anions and/or ligands,'}(E) filler being different from the metal containing component,wherein the catalyst paste comprising (C) a Lewis acid, the composition optionally further comprises (D) a retarder, and (F) additive(s).2. The composition according to claim 1 , wherein the hardenable compound comprises a backbone containing moieties selected from polyether claim 1 , polyesters ...
