        posted
        Can anyone recommend adhesives that are pretty strong, but easily removable later? For example, I'd like to get some strong neodymium magnets to use for projects and be able to attach them to things that are non-magnetic, like plastic. But I'd have to be able to remove the magnets when I'm done using them for that application. So the adhesive would need to be strong enough to keep the magnets attached to the material through repeated sticking and unsticking of the other side of the magnets to magnetic materials, but also be removable eventually.

        Depending on the surface of the plastic hot melt glue from a glue gun may be the ticket. I've used it for a number of things like this. When you want to remove it work a knife blade between the magnet and the surface and twist. It will generally pop off and the hot melt can be gently scraped off with a razor blade.

        Thanks for your reply @Sparky617. I was hoping for a chemical solution -- some kind of adhesive that could be removed with a solvent that wouldn't damage the other materials. Maybe the hot melt glue would work. I'm not sure the magnets could stand up to working a knife blade in between though -- if uncoated I believe they're pretty delicate.

        I can't say that I'm familiar with neodymium magnets.

        neodymium magnets are far from delicate. I would try a fabric based double back tape , like carpet tape, once its pressed down firmly it sticks like white on rice. but can be removed with mineral spirits easily

        Thanks for the suggestion @nona, that sounds promising.

        I don't think I've ever actually handled them, I've just heard they're brittle and prone to shattering (e.g. if snapped together from too far apart):

        I didn't think to check there before, but I just looked on the K&J Magnetics site that I just linked to (safety page) for adhesive info and they have a whole page about it. Unfortunately, in skimming it (I'll have to take a closer look later), I don't see anything specifically discussing removable or temporary adhesive applications. However, one interesting thing it does say is to NOT use hot glue because the temperature can demagnetize the magnets.

        the article does mention double back tape as a good option

        Yeah, it does. Let me ask you this -- the tape that you recommend, do you have any idea what adhesive is used on it? A lot of the magnets I'd be interested in would be pretty small, and round. I think trying to cut tape to fit them cleanly could be a pain in the neck. But if the adhesive used on that tape can be removed with mineral spirits and I could just apply the adhesive directly, that might do the trick.

        well doc, I don't have any idea of what the adhesive is,
        so be careful with your scalpel Big Grin
        I just had a thought, where I was working, one of the practical jokes that was going around was to super glue someones coffee mug to a table, the only way to remove the mug was to apply a sharp , shearing rap to the side of the mug. evidently the glue has very little shear strength
        Maybe that might work

        Are the magnets strong enough to hold the plastic to the metal surface without any adhesive, you know, like you do with the frig....?
        I think we really need more info.?
        What type of plastic and size.?
        Is the plastic porous.?
        What are you sticking it to.?

        I can't remember the commercial name. But technically we call it "METAL SAT". You can find it on local hardware shop.
