Abstract
A two part system for producing structural reinforcing adhesives is provided wherein one component containing epoxy resin is combined with a second component containing a specified curative system. An aliphatic polyamine, an amidoamine, an alcohol and an adduct of a polyamine and an epoxide are present in the curative system. When a thermally activated blowing agent is utilized, the resulting foam is remarkably uniform in cell structure and has improved strength and modulus. Hollow inorganic microspheres are employed to reduce the density of the thermoset produced from the two part system.
