The Euclid Chemical Company Epoxy coatings are important for protecting surfaces from various types of damage—from scratches and abrasion to chemicals and more. Although they can be used at cold temperatures, epoxy coatings must be handled and applied with special techniques adapted to the environment at hand. Mixing an epoxy resin and a hardener together creates a chemical reaction that produces heat. Both the ambient temperature and the temperature of the concrete affect the epoxy’s rate of reaction and degree of cure. If the coating is applied in cooler temperatures, the epoxy may appear sufficiently hardened, but it will not reach a complete cure or achieve its designed physical properties—ultimately leading it to fail prematurely.
