WebApr 12, 2024 · Heat thins resin, which makes it flow better, but it also hastens the curing process. So, if thinner viscosity is the goal, apply heat to the resin just prior to mixing it with the hardener. Viscosity is the thickness or flow-ability of the liquid resin. It can have a large impact on your success. In thermochemistry, an exothermic reaction is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat. The term is often confused with exergonic reaction, which IUPAC defines as "... a reaction for which the overall standard Gibbs energy change ΔG⚬ is negative."
