Abstract
The present invention relates to an epoxy resin system containing the reaction product of an epoxy resin component and an amine-based curing agent component comprising a first amine component and a second amine component, and a method for producing the epoxy resin system comprising combining an epoxy resin component with an amine-based curing agent component to form an initial epoxy resin composition, the amine-based curing agent component comprising a first amine component and a second amine component; and allowing a chemical reaction to occur between the amine-based curing agent component and the epoxy resin component to form a cured epoxy resin composition. The first amine component is N-(3-aminopropyl) cyclohexylamine and the second amine component is the hydrogenated product of oligomeric structure from the 4,4'-Methylenedianiline process.
