Trying to reattach my foam and was thinking guerilla glue clear epoxy, however I am worried about when the time comes to actually replace the foam if I would be screwed.
I haven't tried to remove it yet and I probably could have done a little better job of it. But, I'm good with the result of this stuff, for a backup/loaner mask.
The epoxy should be fine for the foam to plastic. Shouldn't have issues taking foam off in future, no different than superglue or other glues anyways.
I just had to glue the soft foam back to the firmer foam on several masks and for that, I used 3M High Strength 90 spray adhesive. It doesn't soak into the foam as much as regular glue would.
As a maker, I use the ever loving crap out of Barge contact cement. Used it on fixing tired foam adhesive on a few masks too. It's crazy good if you follow the directions.
I have utilized Super Glue but was very unhappy with the resulting hard blobs inside and on the mask surface. I could feel them under the foam.
IMO use something silicone based. Sil-Poxy should be good. I have also used rubber cement to good results, as posted above.
3M automotive spray adhesive, typically used for interior pieces and headliners. Lightly spray on both surfaces and let cure to tacky then put together. Holds up well without dissolving foam or making hard spots.

By all that is (un)holy, mask well, wear protective gear, and do it outside.
Works great. Lasts a long, long time. Everywhere it is applied to.
The question was what to use not how to use it. Not sure I understand why you had such a reaction. Cyanoacrylate adhesives are pretty foul smelling and the off gassing includes active Cyanoacrylates which if put on the face while still curing (it is not instant curing as most think) theoretically could get those Cyanoacrylate adhesives in you eyes....etc. Spray adhesive if used appropriately is just as valid adhesive for this application since this use is very close what it was developed for in the first place. Overspray can be an issue but that is easily dealt with. I use these products very often and they are quick and easy to use with very good bonding.
Grendel, of no doubt it works well. It lasts well. It get's on every damned thing in the area that you use it. It's sticky as hell, adheres well to all those things the overspray can get on and is a pure sombitch to clean up, IME. I am sure if you use it all the time you are far more familiar. I detect a bit of panty wadding via your reply. Certainly wasn't trying to chap any ass (here).
punkncat, no 'panty wading' honestly wanted to know why you had such a negative (sarcastic) reaction to its use/recommendation. I use it often with great success and did not understand the reaction to its inclusion as an option.
How long does that spray adhesive stuff smell like the drainage pipe of a chemical waste facility? Only time I used it was for carpeting, and it pretty near put me out.
Once cured the smell goes away pretty quickly, depending on specific forumula. So if you are using 77 (general purpose version I keep for simple things like this) it fully bonds in <30 minutes but will out gas [smell] for several hours decreasing as time goes. I'd not use it as an adhesive for this case if I needed use immediately usually within 24hrs smell is pretty imperceptible. Masking for use is pretty easy to prevent issues with over spray and it does not require saturation/high volume to provide good adhesion.
I used the 90 on some masks last week and left them outside for a couple of hours. By the time I brought them inside, smell really wasn't noticeable. But when I used to use in on car interiors, it would linger for much longer due to enclosed space.
For masks, I spray onto plastic knife of cardboard and use knife to spread adhesive onto foam. Faster than masking and easier to control application. As already noted, it gets everywhere and isn't fun to remove.
