The glass transition, Tg, is the temperature at which cured epoxies go from being rigid and glassy to being rubbery and more flexible. Most of us think of cured epoxies as being pretty hard (Shore D) materials; and they are, due to the crosslinked nature of their molecules. But if you heat them up, the molecular bonds relax a bit, become a little more flexible, and while the epoxy is still crosslinked, any given epoxy becomes softer and more rubbery at higher temperatures.
