<p>Curable mixtures containing … … (a) an epoxy resin, … (b) a latent curing agent for the epoxy resin, which does not begin to react until a temperature of at least 80 DEG C has been reached (measured by means of DSC at a heating rate of 10 DEG C/min), … (c) an amine containing at least one amine hydrogen, and … (d) a thiol containing at least one SH group, … where either the amine (c) has at least two hydrogen atoms bonded to one or more nitrogen atoms or the thiol (d) contains at least two SH groups, and where the difference between the reaction maxima in the DSC diagram at a heating rate of 10 DEG C/min is at least 30 DEG C, are suitable for the production of crosslinked products, in particular for the production of flexible prepregs having a noncritical B stage and a very good shelf life.</p> |
