I have something I need to bind strong. Much stronger than super glue, but probably less than gorilla glue, although it's not bad if the bind is that strong. I need it to have a quick setting time, probably within a couple minutes. I need it to be removable by something less than a chisel. It doesn't matter if it's hard or rubbery, but it needs to come off pretty clean or close to it. Something like Sikaflex 227 (has a tensile strength of 245 psi, and tensile-sheer strength of 160 psi), although setting time of that is about an hour. I'm hoping to find something inside of 10 minute set time. Does any such adhesive exist?

    Can you explain what you are trying to do? Or is this a top secret project? If we knew what you are trying to do, we can help. – Gunner Oct 16 at 15:16

    Your requirements are contradictory. Also, you haven't said what you're bonding. Seems important. – isherwood Oct 16 at 15:52

    What you're gluing to is a really important consideration in which glue will be appropriate. If you can't tell us that, we can't do more than guess. – Nate S - Reinstate Monica Oct 16 at 17:01

    @Francis, if you think the material you're bonding to is irrelevant to the type of glue that would be appropriate, you might want to take a look at the back of any handy glue bottle -- they ALL list which materials they work well with and which they are not compatible with. And you're asking for a high strength bond, and the strength of adhesion of ANY glue is going to vary based on what it's adhering TO. So the only possible answer to your question as currently worded is "it depends". – Nate S - Reinstate Monica Oct 16 at 17:19

    Really? Combined, the folks here have years and years of experience (way more than you have been alive.) if you say what materials you are bonding, someone might have done it, helped someone do it, used a product for.... With your vauge description, nobody is going to be able to help you. I am voting to close this topic. – Gunner Oct 17 at 9:40

If you need a glue glue, then cyanoacrylate may fill the bill. It's extremely strong (though has narrow tolerances for the mating surfaces, e.g. it can't bridge across gaps), and it removes with acetone. However, acetone can discolor or soften many surfaces.

If you are looking for a method to attach things to surfaces you can't afford to damage, then you should be using the higher tier of Gaffer tape. Gaffer tape is for temporary attachment of portable lighting in cinema/TV/ENG production, say you're interviewing the CEO in his office, but the room doesn't have nearly enough built-in lighting to shoot. So you need strong tape to secure some EyLights to his bookcase, and then, you need the tape to come off cleanly.

That's what gaffer tape does. That is its one job.

  • Do not put this on painted walls!!! – DMoore Oct 16 at 16:16
  • @DMoore, gaffer tape won't damage painted walls unless the paint was in bad condition to begin with (which I have seen happen, like with new latex paint over an improperly prepped surface). But any reasonably durable paint will be fine -- I've done it hundreds of times. Or were you referring to cyanoacrylate/acetone as the thing that should not go on walls? – Nate S - Reinstate Monica Oct 16 at 16:59
  • I agree that cyanoacrylate is a good choice (provided it is reasonably well suited for the materials being glued) but OP said Much stronger than super glue. – manassehkatz-Reinstate Monica Oct 16 at 17:01
  • That almost sounds perfect, but this: "Cyanoacrylate glue has a low shearing strength, which has led to its use as a temporary adhesive in cases where the piece needs to be sheared off later". I would definitely need something with a high shearing strength. – Francis Oct 16 at 17:03
  • The Sikaflex 227 has a tensile strength of 245 psi, and tensile-sheer strength of 160 psi. That is definitely strong and durable enough for what I'm after, just looking for something that sets faster. – Francis Oct 16 at 17:05
