摘要
The disclosure relates to at least one partially reacted product of an isocyanate and an amine (e.g., a reaction product comprising at least one adducted compound). The reaction product comprises polyurea oligomers. The reaction product can be combined with at least one amine in order to formulate a curing agent for epoxy resins wherein the cured epoxy resin has enhanced fracture toughness. The at least partially reacted product does not increase the viscosity of the curing agent and is at least partially soluble in the amine component of the curing agent.
