All adhesives outgas as they dry (that's why they stink). Adhesives
around optics are a true disaster unless you know what you're doing.
Some of the lightweight high-strength plastics that have been
appearing in consumer products the last few years have interesting
foibles. I got a pair of prescription lenses in Ray-Ban frames a few
years gack. After putting the lenses in, they washed everything with
acetone (evidently a common optometric practice). Literally, in front
of my eyes, the frames began disintegrating and popping apart. It was
bizarre, like a special effect in a sci-fi movie. Needless to say,
they found another set of frames for me

Wow, I'm amazed they used acetone! It's death on many plastics,
though usually it just dissolves them.
I've had somewhat similar problems with cyanoacrylate accelerator,
which I believe is an alcohol, getting on certain kinds of plastic. I
used some in the repair of a crack in a clear plastic meter face, and
the face, over the next few days, developed a whole mess of little
cracks. Ooops.
One of my favorites these days for repairing plastic and other broken
things is "Plas-T-Pair" from Rawn Corp. It can be a bit hard to find,
but it's been well worth the hunt for me. It's a two-part system,
powder and liquid. Unlike with cyanoacrylate adhesives, I haven't had
trouble with it outgassing and leaving residues all over the place,
though as Tim says, be careful around optics.
Cheers,
Tom

That's EXACTLY the kind of advice we'd want in the record for the NEXT
