Which thermodynamic effect dominates when epoxy adhesive's crosslinking nears completion?

💡 Explanation

When epoxy adhesive reaches high conversion, highly exothermic polymerization proceeds because freed energy converts chemical bonds into heat, and heat raises temperature, self-accelerating curing speed. Therefore heat generation accelerating curing is most important, rather than cooling, entropy, or enthalpy, each requiring different thermochemical mechanisms.
