For the most part, epoxy resin will resist scratching, scuffing, and other minor damage. Because it is basically just a very strong glue, any kind of epoxy will dry to a hard and durable finish. However, your results will depend partly on the thickness of the epoxy layer. The thicker the layer, the harder it will be to scratch the wood.
For instance, some wooden floors are coated with epoxy for extra longevity. All of these floors have a 2mm layer of epoxy, and anything less is not considered to be a true epoxy floor. Thus, you may need to use more of the stuff in order to get a truly durable result.
