Is the strongest or stiffest adhesive always the best choice?
15 May 2026
No. For surface‑bonded fasteners, the balance between stiffness and flexibility is often more important than peak strength.
Over‑stiff adhesives can increase stress concentrations, particularly on thin or flexible substrates. Tougher or more compliant adhesives may reduce peak stresses and improve durability under cyclic or peel‑sensitive loading.
