Abstract

Hardenable or polymerizable epoxy resin-based composition, characterized in that its hardener system comprises a combination in synergic quantities of: (i) at least one imidazole which, alone, can cause the polymerization of the epoxy resin only at a temperature above about 75.degree. C., (ii) at least one polyamine compound which, alone, leads to the polymerization of the epoxy resin at a temperature lower than about 75.degree. C. Such a resin is particularly suitable for the manufacture of composite structures, applicable in particular in ship- or boatbuilding.
