What glue is best to fix this crack in my phone case?

August 5, 2024 6:48 AM

I have a phone case with a hard polycarbonate component that has a crack in it that can be pushed into place but will pop out again as soon as I let go. What type of glue or epoxy should I use to make the most restorative, durable, and low-profile (in that order of priority) repair ?

Any cyanoacrylate based superglue will work well for polycarbonate. I highly recommend not using any gel versions. I think they stink. Just buy any brand name liquid superglue. I like the ones that come with like 4 tiny little tubes in one pack. It will set very fast and hold well.

I just fixed the snap face of a head torch with Sugru. It's holding fine . . . after 10 days. I rolled out a couple of 1mm sausages of the stuff for mortar, then trimmed the excess with a penknife. I like Sugru because there is no chance that klutzy me will glue my eyelid shut.
