| epoxy | Chemical term describing an oxygen atom bound to two linked carbon atoms Generally, any cyclic ether, but commonly applied to a 3-membered ring; specifically, a three-membered ring is an oxirane, a four-membered ring is an oxetane, a five-membered ring is an oxolane, and a six membered ring is an oxane; oxiranes are commonly produced from peracids acting on alkenes. Epoxys are important chemical intermediates, and the basis of epoxy resins (polymers) formed from epoxy monomers. (05 Mar 2000) |

| epoxy resin | Any thermosetting resin based on the reactivity of epoxy; used as adhesives, protective coatings, and embedding media for electron microscopy. (05 Mar 2000) |
| epoxy resins | Thermosetting resins based on the reactivity of the epoxide group, which is characterised by toughness, adhesibility, chemical resistance, dielectric properties, and dimensional stability. Several modified types are used as denture base material. (12 Dec 1998) |
