USE OF INHIBITOR COMBINATION, RESIN COMPOSITION, REACTIVE RESIN MORTAR, TWO-COMPONENT MORTAR COMPOSITION, USE OF THE TWO-COMPONENT MORTAR COMPOSITION FOR CHEMICAL FASTENING, AND PATRONE, CARTRIDGE AND FILM POUCH CONTAINING THE TWO-COMPONENT MORTAR COMPOSITION

PROBLEM TO BE SOLVED: To use a mixture of a sterically hindered phenol derivative and a 5-pyrimidinol derivative for adjusting the reactivity and the gel time of a resin composition and reactive resin mortar based on a radically polymerizable compound.SOLUTION: There are provided a resin composition containing an inhibitor composition, reactive resin mortar containing this resin composition, and a two-component mortar composition which includes the reactive resin mortar and is improved in storage stability and low-temperature hardening properties. The resin composition is suitable in particular for chemical fastening of various underground structural parts in boreholes.
