Yesterday's entry on epichlorohydrin got us halfway to an epoxy resin, with the aid of good old bisphenol A. In that other tube, you'll often find some sort of amine, which, when mixed with a prepolymer like that formed with epichlorohydrin-bisphenol A, heats up and hardens.
This triamino-phenol is one hardener found in epoxy adhesives. It reacts further with the epichlorohydrin, giving a cross-linked, hard (or just firm) epoxy resin. It's also responsible for the smell you probably associate with epoxy.
