Definition of Epoxy: 1  Epoxy is a class of resin derived by polymerization from epoxides. 2  Epoxy is a thermosetting resin capable of forming tightly linked cross-polymer structures. 3  Epoxy is characterized by toughness and strong adhesion, especially when used for floor coatings.
Epoxy is a substance that requires the addition of a hardener. The hardener interacts with the epoxy and creates heat, that hardens the material and sets it in place. Too much heat can cause the epoxy to crack, so multiple thin layers should be applied to your countertop rather than one thick layer.
