How should you think about the temperature resistance of the adhesive for a bonded assembly

You need to ask yourself the following questions 

How cured is the adhesive?

What is the absolute magnitude of temperature that will be seen in the application?

How long does the assembly see those temperature extremes and every point in between?

What is the actual load being applied the to the adhesive while it's exposed to the temperature?

Specifically, as temperature increases past a certain point (The Glass Transition Temperature) it will go from a glassy rigid state through a transition to a softer rubbery state. Physical properties of the adhesive will change as it warms and cools through the transition stage, including rigidity, thermal expansion coefficient and heat capacity, among others, and this can affect the load bearing ability of the adhesive.
