N-HYDROXYL ETHYL PIPERIDINE (NHEP): A NOVEL CURING AGENT FOR EPOXY SYSTEMS

The present invention relates to an amine-based curing agent comprising at least 1% by weight of at least one tertiary amine and, optionally, primary and/or secondary amines. The tertiary amine is preferably an N-substituted piperidine tertiary amine and, more preferably, N-hydroxyethyl piperidine (...

Zusammenfassung:The present invention relates to an amine-based curing agent comprising at least 1% by weight of at least one tertiary amine and, optionally, primary and/or secondary amines. The tertiary amine is preferably an N-substituted piperidine tertiary amine and, more preferably, N-hydroxyethyl piperidine (NHEP). The present invention also relates to an epoxy resin composition formed using this amine-based curing agent and a method of making the epoxy resin composition. These tertiary amines enhance desirable properties of epoxy resin compositions without the negative impact on mechanical properties in the cured product normally seen with tertiary amine-based curing agents.
