epoxy

noun    (Concise Encyclopedia)

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.
