Glue bonds to nonstick surfaces and wipes clean with ethanol(cen.acs.org)

Isn't high-ductility associated with creep, especially under static loads? That would seem to be a downside of an adhesive like this.

Could this be used for hanging things from walls without damaging them?

In what context would one re-use a glue like this?

I have a weird use case, but this is actually wildly useful to me.

I use teflon (sometimes nylon, but mostly teflon) painter pyramids/holders/etc, because i spray finish stuff that is very good at adhering to lots of things, and are acetone based - VOC compliance pretty much forced acetone into solvent based stuff. This in turn pretty much makes finishes melt into anything except PE, nylon, teflon, even if they wouldn't otherwise.

To keep the pyramids and things where i want them, i have magnets glued into them. But because it's PFTE, the magnets don't really stay adhered well, even with (currently) specialized adhesives and i end up regluing them after every few times, often before the project finishes.

What i really want is an adhesive like this one, where i can glue the magnets in, but also remove them after the project finishes, because i'll go soak the pyramids in solvent or something to clean them, but don't want to damage any magnet coatings.

I would 3D print (FDM) standoffs in PE with integrated pockets to insert magnets. You can even insert the magnets during the print if you fancy. Though my preference goes to a slide in pocket.

PE sticks to itself and not much else. Packing tape is PE and adhesive. Apply PE tape to the printer bed before printing.

Yeah I have been playing with 3d printing nylon and pps versions because pure pe filament are harder to find. They also often have really really poor layer adhesion and crazy levels of warping.

PPS is not that expensive if you know some of the more specialized filament vendors.

Anyway like I said my use case is weird and may even be transient.

I can think of other use cases, but most are coatings related (Ie using Teflon as a removable masking material, etc).

The removability is actually much less interesting than the ability to strongly bond Teflon.

Is there really a use for this(temporary adhesives) outside of Fixturing?

The marine industry would love a (non water soluble) glue that achieves structural strength on PTFE and POM.

Are you asking if there's use for temporarily sticking stuff to other stuff?

Yes, plenty. Especially if it sticks well while needed, and then can be non-destructively undone when no longer needed.

That is generally what fixturing implies. A temporary bond that you use while making a part, and then remove when the part is complete.

I think it could also be used outside of making a part. For example you want to setup sensor on a surface but it's important not to damage the surface, like the outside of a boat. This would be excellent for that.

This might be very useful for bonding PTFE and aluminium on cookware if it ends up being food safe.

Any reason to think this flower of fluorines (seriously, that thing looks INTENSE) would be any more environmentally safe than PFOA?

On the left hand side we see a lot very unhappy carbon.
