摘要： A curing composition is useful for a multi-component epoxy resin compound and includes at least one first poly amine, at least one second polyamine, and at least one polyphenol from the group of bisphenols and novolac resins as an accelerator. Upon contact with atmospheric oxygen, the curing composition discolors within a few days and therefore leakages can be visually identified.

摘要： A curing agent component is useful for a multicomponent epoxide resin composition. An epoxide resin composition produced using the curing agent component, wherein the curing agent component includes, as a curing agent, at least one Mannich base and an amine that is reactive with respect to epoxide groups, as well as at least one polyphenol from the group of novolac resins as an accelerant. The Mannich base can be obtained by reacting a phenolic compound selected from the group consisting of phenol, styrenated phenol, catechol, resorcinol, hydroquinone, hydroxyhydroquinone, phloroglucinol, pyrogallol, o-cresol, m-cresol, p-cresol and bisphenols, with an aldehyde or an aldehyde precursor and an amine having at least two active hydrogen atoms in the molecule which are bonded to a nitrogen atom. The novolac resin is contained in the curing agent component in a proportion of from 5 to 30 wt. %, based on the organic proportions of the curing agent component.

摘要： Epoxide-acrylate hybrid molecules include a polyol backbone, at least one epoxy group, and at least one acrylate group. A method of chemical anchoring is developed using the epoxide-acrylate hybrid molecule in the resin component of a multi-component reactive resin composition. A method of improving the stability of mortars is developed by adding the epoxide-acrylate hybrid molecule to a multi-component reactive resin composition. Furthermore, a multi-component reactive resin composition includes these epoxide-acrylate hybrid molecules, and to the use of such a multi-component reactive resin composition for chemical anchoring.
