A curing agent component is described for an at least two-component mortar composition for the chemical fastening technique, containing at least one free radical-forming agent as curing agent for an organic resin component, water and at least one water-soluble, ethylenically unsaturated polyethylene glycol derivative, which can be copolymerized with the organic resin component and has a solubility in water at 25°C of at least 10 g in 100 gram of water and has the structure given by the general formula I: R2-A-O-R1 (I) in which R1 represents a group having the formula CH2=CH-CH2-, CH2=CH-CO-O- or CH2=C(CH3)-CO-O-, R2 represents hydrogen, an alkyl group with 1 to 6 carbon atoms, a sulfonate group or a group having the formula CH2=CH-CH2-, CH2=CH-CO-O- or CH2=C(CH3)-CO-O-, and A represents a linear or branched, homopolymeric or copolymeric, optionally substituted polyoxyalkylene group. Furthermore, methods are described for producing and using the curing agent component in a two- component or multi-component mortar composition for fastening construction elements in a solid substrate.
