Abstract: 
The sealed joint is composed of materials which vary in modulus, elasticity, chemical stability and thermal expansion. A thorough knowledge of the interaction of this system of materials in response to external stresses is fundamental to the understanding of sealant adhesion and durability. This chapter focuses on the changes in interfacial stress balanced against the changes in interfacial strength of the sealed joint. The authors present a short overview of adhesion science. This is followed by a review of the recent literature covering ageing effects on the interfacial strength of the sealant joint. Changes in the internal stress of the sealed joint as a function of ageing are then reviewed. Finally, the sealant adhesion durability is discussed in terms of the ageing effects on the interfacial strength and the bulk stability of the sealant. Additionally, practices for measuring interfacial strength are reviewed.
