Abstract
Use of a synthetic resin system as an adhesive for chemical fixing technology, especially for fixing anchoring means in drilled holes, which synthetic resin system includes a) a reaction resin based on α, β-unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a catalyst, and to related subject matter.
Claims13
A method for fixing of an anchoring element in a hole or crevice in a building substrate, comprising introducing a synthetic resin system as an adhesive in the form of a two-component kit as a cartridge or a foil pouch, each having two chambers, wherein the synthetic resin system includes a) a reaction resin based on α, β-unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a catalyst;
- said method further comprising introducing the synthetic resin system and an anchoring element one after the other or substantially simultaneously into said hole or crevice,
- wherein the synthetic resin is a Michael-addition-hardening and wherein the catalyst is selected from the group consisting of alkali metal hydroxides, alkali metal alkoxides, quaternary ammonium compounds, tertiary amines, guanidines, amidines;
- phosphine catalysts;
- and catalysts in the form of mixtures of an epoxide with one or more tertiary amines, it being possible for salts of strong bases or small amounts of the strong bases themselves additionally to be added;
- or a mixture of two or more of the catalysts.
