Which consequence results when an uncured epoxy coating system experiences significant thermal cycling on a steel I-beam?

💡 Explanation

Thermal cycling causes differential thermal expansion between steel and the coating, leading to interfacial shear stress and eventual disbondment; because cohesive failure does not have time to set. Therefore, adhesive failure weakens the coated steel rather than galvanic protection.
