PROBLEM TO BE SOLVED: To produce a prepreg based on an epoxide and a polyamine crosslinking agent as a crosslinking agent and a curing agent for a resin composition and to produce the same. Crosslinker formulations consisting of liquid polyamines based on trimerized toluylene 2,4- and / or 2,6-diisocyanate with hydrolysis to isocyanate groups and amino groups are not further condensed. 5-tris- (3-isocyanato-4-methyl-phenyl, 2-methyl-3-aminophenyl) isocyanurate at 40-80% of the total weight and toluylene 2,4- and / or 2,6 It contains no more than 1.0% of the total weight of the diamine. |
