Abstract
The invention relates to a curable dental composition being prepared by mixing a base paste and a catalyst paste, 'the base paste comprising component(s) (A) with curable moieties (AC),' the catalyst paste comprising a catalyst (C) being able to initiate or catalyse a crosslinking reaction involving components (A) upon mixing base paste and catalyst paste, the curable composition comprising a component (X) with reactive moieties, component (X) being either produced during the curing reaction or being present in either the base paste or the catalyst paste before the crosslinking reaction is initiated or catalysed, component X being different from component(s) (A), either base paste or catalyst paste comprising a reactant (Y), reactant (Y) being able to interact with component (X), but not taking part in the crosslinking reaction, the curable composition being able to produce energy in an amount sufficient to increase the temperature T1 of the composition being present 20 s after mixing the base paste and the catalyst paste to a temperature T2 being from about 6 to about 20° C. above T1.
