A curing agent composition based on diaminomethylcyclohexane and 1,3-cyclohexanebis(methylamine) can be used in an epoxy resin composition for chemical fastening of structural elements. A corresponding epoxy resin composition and multi-component epoxy resin system can contain the curing agent composition. A method can be used for chemical fastening of structural elements in boreholes with the epoxy resin composition or the multi-component epoxy resin system.

Curing agent composition based on diaminomethylcyclohexane and 1,3-cyclohexanebis(methylamine) for an epoxy resin composition, epoxy resin composition, and multi-component epoxy resin system

A method includes using at least one salt (S) selected from the salts of nitric acid, salts of nitrous acid, salts of halogens or salts of trifluoromethanesulfonic acid as an accelerator in a multi-component epoxy resin compound for the chemical fastening of construction elements and/or anchoring means. Another method includes the chemical fastening of construction elements and anchoring elements, such as anchor rods, anchor bolts, rods, sleeves, reinforcing bars, screws and the like in boreholes in various substrates.

Use of salts as accelerators in an epoxy resin compound for chemical fastening

A hardener component is useful for a multi-component epoxy resin material, and includes a benzoxazine amine adduct as an accelerator and an amine as a hardener. The benzoxazine amine adduct is present in the hardener component in a proportion of from 8.5 wt. % to 75 wt. %. The multi-component material including the benzoxazine amine adduct in the hardener component already has a quick curing time at room temperature and can therefore be used advantageously for the chemical fastening of construction elements.

Hardener component for multi-component epoxy resin material, and multi-component epoxy resin material

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 he obtained by reacting a phenolic compound selected from 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 5-30 wt. %, based on the organic proportions of the curing agent component.
