Abstract
Disclosure is made of a method of curing the polyepoxide resin binder component of polyepoxide based syntactic foams of high density. Ketones are employed to reversably block primary amine groups on polyamine curing agents during the initial curing. As the cure progresses, the block is removed to complete the cure. The result is a moderation of peak exotherms generally associated with the cure, inhibiting degradation of the product foam.
