Beschreibung
Zusammenfassung:	The present invention relates to novel latent curing agents for curing curable polymer resins, in particular epoxy resins, and to epoxy resin compositions and the use thereof in the production of fibre composites. The liquid curing agent for curing polymer resins, comprising a) Cyanamide; b) at least one urea derivative of Formula (l) (see formula I) wherein the following apply, simultaneously or independently of one another, to the radicals and at least one defined radical R1, R2, R3 that is not hydrogen: and c) at least one viscosity modifier selected from the group of the monools, diols and/or polyols, ethers, polyethers, polyether polyols, ketones, aldehydes, nitriles, carboxylic acid esters or mixtures thereof. Nouveaux durcisseurs latents pour le durcissement de résines polymères durcissables, en particulier de résines époxydes, ainsi que compositions de résines époxydes et leur utilisation pour la production de matériaux composites renforcés par des fibres.
