There are several adhesives that cure with UV light.
Essentially they all break one type of bond upon
exposre to UV light and make a more light stable bond.
 Different adhesive systems may use slightly diffreent
chemical systems to acheive this.  Epoxies and
cyanoacrylates are consdered thermoset type systems,
being activeated by heat. And room temperature is
often more than enough to make these systems activate.
