epoxy

Any of a class of thermosetting polymers, polyethers built up from monomers with an ether group that takes the form of a three-membered epoxide ring. The familiar two-part epoxy adhesives consist of a resin with epoxide rings at the ends of its molecules and a curing agent containing amines or anhydrides. When mixed, these react to yield, after curing, a complex network with ether groups linking the monomers. Stable, tough, and resistant to corrosive chemicals, epoxies are excellent adhesives and useful surface coatings.


epoxy Chem
1. of, consisting of, or containing an oxygen atom joined to two different groups that are themselves joined to other groups
2. short for epoxy resin
