Abstract

Use of a stable indole-nitroxide radical as a stabilizer and/or inhibitor for resin mixtures and reactive resin mortars is described on the basis of radically curable compounds. Resin mixtures and reactive resin mortars may be made stable in storage very effectively using the indole nitroxide radical and the pot life of mortar compositions can be adjusted in a targeted manner.
