A method is useful for producing a urethane(meth)acrylate resin composition. The method improves storage stability and reduces the reactivity drift of the composition compared to compositions made by other means from the same starting materials. In particular, it reduces the degradation of TEMPOL in mixtures with branched urethane resins.

A dispensing unit includes a first sheet-material bag which is filled with a first composition, a second sheet-material bag which is filled with a second composition, and a head part disposed on a first end of the first sheet-material bag and a second end of the second sheet-material bag. The head part has a first outlet channel for the first composition and a second outlet channel for the second composition, the first and second sheet-material bags are open on the first and second ends, and the first and second outlet channels are filled with the first and second compositions, respectively. A closure part is configured to couple with the head part, where the closure part is openable or removable by a user.

The use of ethylenically unsaturated isocyanate derivatives of the general Formula (I) as an agent for covalently bonding impurities, plasticizers and or desensitizing agents, having active hydrogen atoms, is described in curable compositions based on ethylenically unsaturated monomers, oligomers and polymers as resin component and organic peroxides, preferably benzoyl peroxide, as curing agent.

An anchor, which is secured in a bore with a mortar, has an anchor member ( ) located in the bore, a load application member ( ) projecting out of the bore, at least one mixing element ( &prime;) for mixing components of the mortar, a drive element ( &prime;) provided on the anchor member ( ) for setting in motion the at least one mixing element ( &prime;), and a trigger ( ) for actuating the drive element ( &prime;) which automatically sets in motion the mixing member ( ) upon actuation of the trigger ( ).

A curable, two-component mortar composition is described, which is based on a curable epoxide resin, at least one reactive diluent for the epoxide resin, an amine curing agent and one or more inorganic fillers, as well as, optionally, curing catalysts, rheological aids, thixotropizing agents, stabilizers, dispersants, agents to control the reaction rate and wetting agents, the amine curing agent of the curable epoxide resin and the reactive diluent being kept separate from one another to inhibit any reaction, wherein the mortar composition contains a cross-linking reactive diluent, which has functional epoxy groups with an epoxy functionality of at least 2. The mortar composition is used to fasten anchoring means in boreholes.
