Abstract
Foamable compositions based on epoxy resins which exhibit good shelf life are obtained through the use of specific blowing agent and curing accelerator systems. The blowing agent system contains azodicarbonamide, while the curative system contains an amine-epoxy adduct such as an imidazole-epoxy adduct. The compositions are capable of providing structural foams which are useful in the manufacture of reinforced structural members and the like.
