Preparations containing epoxy resin and amine mixtures with guanidine derivatives

Preparation containing α) or more epoxy resins and β) a mixture containing 1) 0, 3 0, 9 equivalents of amine per epoxide equivalent of component a) employed in a curing component a) and 2) a component curing b), characterized in that the curing component a) contains one or more amines having a functionality 2 and that at least one amine in stoichiometric mixed with the epoxy resin in the load of 100 g, at room temperature leads to a time of less than 24 h curing because the curing component b) containing at least one compound of formula I wherein the ratio of curing component b) is 5 to 55% by weight based on the weight ratio of mixture and in formula I, R1 to R3, R5 and R6 independently represent each other an organic radical having 1 to 20 carbon atoms and hydrogen and R4 is chosen from the group of an organic radical having 1 to 20 carbon atoms and a C (NH) NR5R6.
