Abstract: A single component, extremely low viscosity, pre-catalyzed high functionality diepoxide and epoxy resin system has been developed. This resin system has good thermal stability, an extended work life and is capable of being refrigerated to -18 C. and stored for extended periods of time with little or no change in physical or mechanical properties. The resin system has direct applications in a number of industries including, but not limited to, the aircraft and spacecraft industries. The resin system is a mixture of specific epoxy resins and curing agents that when combined form an extremely low viscosity resinous system that may be readily cured at a temperature as low as 52 degrees C. into novel thermoset materials prepared therefrom, which are characterized by superior strength properties and methods for preparing the same.
