Chemical compatibility I'm an electrical engineer trying to understand a failure in a plastic part that I'm working with.

I am using a plastic called polysulfone- and the data sheet has a lot of words ending in "amine" that are listed as not-being compatible with said plastic.

I want to bond this plastic with an epoxy, but the very-vague datasheet states that the hardener contains 80% "Modified Cycloalipathic Amines".

With this admittedly limited information, should I look for a different adhesive?

The process temp is $5$ to $85~^\circ\mathrm{F}$ ($-15$ to $29~^\circ\mathrm{C}$).
I suggest taking the experimental route and exposing another test piece of the plastic you are working with to the hardener. Keep an eye out for any softening, swelling, change of color and any other indicators of a reaction occuring.
