CJH;4617374; said:... Sweetwater is a solvent based epoxy paint so there is not only the endothermic (heat producing) reaction but also an evaporative process as the solvents offgass. With a 100% solids system like West Systems there is only the endothermic reaction and no evaporation.
Sorry, that should read exothermic in both cases, not endothermic.
