Abstract: A mixture includes at least two radically curable compounds as a backbone resin, and is useful in reactive resins. In particular, the mixture reduces the viscosity of such reactive resin-containing mixtures and thus the dispensing forces required for ejecting the reactive resin components produced therefrom. The mixture also increases the performance of the reactive resins containing such mixtures and of the reactive resin components produced therefrom. Further, said reactive resins and the reactive resin components thereof are useful for construction purposes, in particular for chemical fastening.

Abstract: A hardener composition can be used for a reactive resin system containing a reactive resin based on radically curable, ethylenically unsaturated compounds. The hardener composition contains a hardener for the reactive resin and a filler mixture. The filler mixture is composed of a first filler having a first average particle size d50,1 and a second filler having a second average particle size d50,2. The first average particle size d50,1 of the first filler is greater than the second average particle size d50,2 of the second filler (d50,1>d50,2). The ratio d50,1 to d50,2 (d50,1:d50,2) is in the range of 8:1 to 100:1. The filler mixture is useful, and a reaction resin system can contain the hardener composition.
