Slow exothermic reaction
WebbThe chemical reaction between resin and hardener as epoxy cures will generate heat. When this heat cannot escape, it builds up, causing the epoxy to cure faster because epoxy cures faster at higher temperatures. Curing faster because of the heat, the epoxy generates even more heat, even faster. Webb26 maj 2024 · Exothermic reactions are chemical reactions that release energy as heat or light.
