Patent ID: 8852489

Claim:
A process for producing a molding, the process comprising: (I) introducing, into a mold, a blend comprising (A) an epoxy resin, and (B) a mixture comprising i) a first hardener component comprising an amine (a1) having a functionality ≧2, and ii) from 5 to 30% by weight, based on a total weight of the mixture, of a second hardener component, which is a compound of formula (I): wherein R1, R2, and R3 each independently stand for an organic radical comprising 1 to 20 C. atoms and hydrogen, and R4 is an organic radical comprising 1 to 20 C. atoms or a group —C(NH)NR5R6, wherein R5 and R6 each independently stand for an organic radical comprising 1 to 20 C. atoms and hydrogen; and then, (II) curing the blend in the mold, wherein the blend contains 0.4 to 0.9 amine equivalent, per equivalent of epoxide of the epoxy resin present in the blend, of the amine (a1) of the first hardener component, which when mixed stoichiometrically with the epoxy resin in a 100 g batch, has a cure time of less than 24 h at room temperature.
