Longman Dictionary of Contemporary English

epoxy

1916, in reference to certain chemical compounds, from epi- + first element of oxygen. Epoxy- is used as a prefix in chemistry to indicate an oxygen atom that is linked to two carbon atoms of a chain, thus forming a "bridge" ("intramolecular connection" is one of the chemical uses of epi-). Resins from epoxides are used as powerful glues. Hence the verb meaning "to bond with epoxy" (1965). Related: Epoxied.

Epoxy

Epoxy is a term used to denote both the basic components and the cured end products of epoxy resins, as well as a colloquial name for the epoxide functional group. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. Epoxy resins may be reacted ( cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols. These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with high mechanical properties, temperature and chemical resistance. Epoxy has a wide range of applications, including metal coatings, use in electronics / electrical components/LED, high tension electrical insulators, fiber-reinforced plastic materials and structural adhesives.
