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 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.

Multicomponent epoxide resin composition and curing agent component therefor

A curing composition for an epoxy resin compound useful for the chemical fastening of construction elements, an epoxy resin compound, and a multi-component epoxy resin system are provided. A method for the chemical fastening of construction elements in boreholes and a method of using a salt (S) as an accelerator in an epoxy resin compound for chemical fastening, the epoxy resin compound including a Mannich base and an amine which is reactive to epoxy groups.

Curing composition for an epoxy resin compound, epoxy resin compound and multi-component epoxy resin system

A curing composition is useful for a multi-component epoxy resin compound and includes at least one first polyamine, 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.

Multi-component epoxy resin compound with leakage indicator, and curing component for the epoxy resin compound

The invention relates to a curing agent composition for an epoxy resin compound for the chemical fastening of construction elements, to an epoxy resin compound, and to a multi-component epoxy resin system. The invention further relates to a method for the chemical fastening of construction elements in boreholes. The invention also relates to the use of a salt (S) as an accelerator in an epoxy resin compound for chemical fastening, the epoxy resin compound comprising 3-aminomethyl-3,5,5-trimethylcyclohexane and at least one further cycloaliphatic amine which is reactive to epoxy groups.

Curing agent composition for an epoxy resin compound, epoxy resin compound and multi-component epoxy resin system

A method or apparatus for examining a security element of a value document involves at least one optical property of the security element influenceable by a magnetic field. The value document is transported through a magnetic field which is inhomogeneous transversely to the transport direction and/or is changed time-dependently. An image of at least one portion of the value document having the security element is captured and image data describing the image are formed. The optical properties of the security element are influenced by the magnetic field, and the image data is checked whether they have a location dependence transverse to the transport direction corresponding to the location dependence of the magnetic field and/or have a location dependence in the transport direction corresponding to the time dependence of the magnetic field.
