Definition(s)
Epoxy
Compound containing at least two epoxy or oxirane rings.
- Note: 1 to entry: Chemically, an epoxy ring is a three-membered ring containing two carbon atoms and one oxygen atom.
- Note: 2 to entry: The most widely used epoxy resin is termed DGEBA (diglycidyl ether of bisphenol A). Epoxy resins are always used in conjunction with curing agents or hardeners, i.e. substances that react with the epoxy rings, producing hydroxyl groups and other products, and linking the originally linear molecules into a rigid three-dimensional network.
