Abstract
The use of a mixture of 5-pyrimidinol derivatives with sterically hindered phenol derivatives for adjusting the reactivity and the gel time of resin mixtures and reactive resin mortars based on radically polymerizable compounds is described. Furthermore, a resin mixture containing the inhibitor combination, a reactive resin mortar containing this resin mixture and two-component mortar systems with the reactive resin mortar according to the invention and a hardener with improved stability in storage and good low-temperature hardening properties are also described. The resin mixture according to the invention is suitable in particular for chemical fastening of construction elements in boreholes in various substrates.
