Curing agents - composition for the curing of epoxy resins, epoxy resin - composition with the curing agent - composition and use of the curing agents - composition

摘要

The present invention relates to a curing agent - composition for the hardening of epoxy resins, comprising: a) of cyanamide and b) at least an amine derivative having two or more primary and / or secondary amine groups, wherein the curing agents - composition of from 2 to 5 wt.% of cyanamide and of 98 to 95 wt.% of the at least one amine derivative contains. The present invention also relates to an epoxy resin - a composition comprising a) at least one epoxy resin and b) at least one hardener - a composition according to the present invention, wherein the epoxy resin - composition of from 75 to 85 wt.% of epoxy resin and 25 to 15 wt.% hardener - composition contains. By the use of an aliphatic trifunctional glycidyl ether as reactive diluents, the viscosity of the epoxy resin as the accelerator and lowered by means of the cyanamide acting in the a curing agent composition the cycle time can be shortened. The curing agents - composition and the epoxy resin - composition are particularly suitable for the production of composite fiber materials by means of an infusion - or injection method.
