Which outcome limits epoxy resin curing at lower temperatures?

💡 Explanation

Reduced temperature lowers molecule kinetic energy, therefore reduces the frequency of effective collisions needed for the nucleophilic substitution reaction. This limits crosslinking, because reactant energy is too low for activation energy, rather than faster secondary chain growth.
