Adhesives are sometimes used as load bearing and sealing joints, which points great stress on them.
In accelerated testing, factors like the temperature, moisture, vibrations, voltage, and UV light are greatly increased over a short period so long term predictions can be made about the effect of the aforementioned factors.
[1][3] Adhesives commonly react with oxygen at low temperatures, which leads to a slow break down of polymer chains.
Chemiluminescence (CL) light intensity can be measured at various isothermal oxidation cycles; however, the temperature need not be raised to high levels.
By obtaining measurements at different temperatures, an accelerated oxidation progression correlation can be established.
