Epoxy resins are cured with the addition of a curing agent, commonly called a hardener. Perhaps the most common type of curing agent is amine-based. Unlike in polyester or vinyl ester resins, where the resin is catalyzed with a small (1-3%) addition of a catalyst, epoxy resins usually re...
A thermosetting resin or thermoset is a polymer that cures or sets into a hard shape using curing methods such as heat or radiation. The curing process is an irreversible process. It introduces a polymer network crosslinked by covalent chemical bonds. ...

An epoxy resin is defined as a molecule containing more than one epoxy group capable of being converted to a thermoset form. The term, epoxy, is used to indicate the resins in both the thermoplastic (uncured) and thermoset (cured) state. Epoxy functional groups are prepared (1) by the rea...

Epoxy resins have been used extensively in commerce to prepare hard thermoset solid polymeric compounds. Their use is widespread in many industries, notably, the electrical and aerospace industries. They are used, for example, in protective coatings, coatings, adhesives, structural composites, and lami...
