One of the most important requirements of an adhesive joint is the ability to retain a significant proportion of its properties under the wide variety of environmental conditions that are likely to be encountered during its service life. One of the most aggressive and hostile environments for any adhesive is the combination of high humidity and high temperature and many automotive customers now demand performance after 1000 hours at 85 °C and 85% RH.

Durability of adhesives is also discussed in Sections 9.3 to 9.6 and this is perhaps the most difficult area to troubleshoot as, by its nature, it is likely to be some time after the component parts were assembled that a troubleshoot is required. It will almost certainly be necessary to include in any investigation into the loss of performance the three factors described above (no glue, no cure, no stick). The next step is to examine the adhesive bond line.
