While this is not strictly metal related, I'm sure I will get some
good advice here.
I need to stick tiny (about 1/8th inch dia) rare earth magnets to
plastic film (think laminated paper) and I am looking for a glue to do
the job. The result needs to be fairly difficult to break.Tried CA,
but I can break the bond with some effort. Same with Araldite
(epoxy).
Any suggestions? Any tips to get it to work better?
TIA - I'm back to lurking now

It depends entirely on what kind of plastic film you're dealing with. In
some cases, there is no adhesive that will produce more than a superficial
bond.
You really have to know what the plastic is. There's no getting around it.

Please log in for more thread options Just used some of this stuff to glue a magnet to some "King Board" in my
trailer, double sided acrylic body trim tape didn't stick at all but this
seems to be holding so far:

Think it's the same family of adhesives as "shoo goo". It's a little
flexible but should do the job...

And the magnet. The rare-earth alloys are highly prone to rust, and many
of the magnets are chrome plated. In addition to the difficulty of
sticking to the plastic, you may need a glue that can handle the chrome
plating.
OP: Are these magnets chromed? Are you having trouble with the bond to
the magnet, or the bond to the plastic/paper?

How about placing a "twin" magnet on each "side" of the plastic, with
say some glue under each. That should almost double the strain
required to remove one.
