CYCLOALIPHATIC AMINES FOR EPOXY FORMULATIONS: A NOVEL CURING AGENT FOR EPOXY SYSTEMS

摘要

The present invention related to an epoxy curing agent comprising a first amine component and a second amine component. The present invention also 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. The present invention also relates to a method for producing the epoxy resin system comprising combining an epoxy resin component with an amine-based curing agent component, the amine-based curing agent component comprising a first amine component and a second amine component; and reacting 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. The second amine component is the hydrogenated product of oligomeric structure from the 4,4'-Methylenedianiline process. N-(3-aminopropyl) cyclohexylamine enhances desirable properties of epoxy resin compositions without the negative impact on mechanical properties in the cured product normally seen with cycloaliphatic amine-based curing agents.
