When UV light hits the cured epoxy resin, whether directly or indirectly, the natural process of degrading the polymers within is sped up. This photochemical reaction is responsible for more than just turning the epoxy resin yellowish.

Can you melt cured resin and reuse it?

NO, the resin cannot be melted and reused. It cannot even be melted. Asking at what temperature does resin melt doesn't work in the literal sense, but does make sense in looking at the point of decomposition.
