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.

Yesterday's entry on epoxides may have brought to mind epoxies. The similarity isn't a coincidence. Chloromethylepoxide, or "epichlorohydrin," is the basis for many epoxy adhexives.
It's one of those hitch hiking deals:
The KISS is running a mini-workshop at KITP on doing Exoplanet Science Measurements from Solar System probes.
I'm on vacation this week, and taking this opportunity to clear out a large backlog of news items that I flagged as interesting, but never got around to commenting on.
