The answer to whether epoxy and resin are the same is twofold. Epoxy and resin are similar because both are adhesives. However, the difference between epoxy and resin is mainly due to drying time. All epoxies are resins, but not all resins are epoxies. Therefore, when epoxy gets added to a resin, you get epoxy resin, which is an excellent resin to use when doing arts and crafts. Epoxy dries much faster than standard resin and is also more hardened.
