Epoxy or super glue, which is stronger?

depends on the application. how it adheres to the surfaces is really key.

It depends.

Epoxy is superior in nearly all situations, I would imagine.

cyanoacrylate isn't really very durable.

Those other adhesives aren't "true" "super-glue" or CNA. They are different, and like some said, depending on the surface can be superior. Epoxies are generally a must if the surfaces are porous.

Yeah. That's why I said nearly. ;)

Epoxy is superior to CA. CA is nearly always misapplied. Epoxy has a higher tolerance to misapplication thus is much less likely to fail under such circumstances. I've used Belzona epoxies to repair parts on various aircraft and spacecraft where welding would be inappropriate! Belzona epoxy is without a doubt the best there is. Too bad you cannot purchase it in Home Depot.

The closest thing you can get though is PC-7.

Cheers!
