Which mechanism compromises the structural integrity of epoxy adhesives at elevated temperatures?

💡 Explanation

Elevated temperatures accelerate moisture permeation and therefore cause thermally-induced hydrolytic degradation of the ester linkages in the epoxy. This scission weakens the polymer matrix, because hydrolysis breaks the covalent bonds rather than just disrupting intermolecular forces.
