In heat-cured epoxy adhesives, which outcome results from incomplete curing?

💡 Explanation

Incomplete curing prevents full polymerization; reduced cross-linking density then occurs because fewer covalent bonds form between polymer chains. Consequently, mechanical strength is lowered, therefore choice A, rather than enhanced wetting or increased conductivity.
