摘要:
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.

摘要:
Hydraulic cement set-accelerating admixture compositions; cement compositions containing such admixtures; and methods for preparing said cement compositions. The admixture compositions comprise one or more nitroalcohols present in an amount effective to increase the set acceleration of a hydraulic cement composition. The invention further relates to a method of making a hydraulic cement composition comprising adding to a cement composition comprising a hydraulic cement binder, a nitroalcohol component in an amount effective to increase the set-acceleration of the binder, and to a cement composition comprising a hydraulic cement binder and a nitroalcohol set-accelerating agent.

摘要:
The use of a combination of at least one stable nitroxyl radical and at least one quinone methide as a stabilizer for resin mixtures and reactive resin mortars, each based on radically curable compounds, is described. Resin mixtures and in particular reactive resin mortars may be combined very effectively with a combination of at least one stable nitroxyl radical and at least one quinone methide to make them stable in storage.
