Who says this will be a specialized adhesive? If it works as advertised, it could be a super-glue alternative with easy unglueability. That would be an attractive consumer product; and the type of product that could easily end up on someones hands.

Superglue is probably two order of magnitude stronger, so I doubt that this will replace cyanoacrylates. And while ethanol or hand sanitizer will not help much with superglue, acetone or nail polish remover will remove it. Then again, acetone will attack more materials then ethanol, so a glue that can be removed with ethanol might still be beneficial.

There's an endless stream of non-stick pans in Goodwills. I feel bad for the people that don't know better and buy used non-stick pans and I also feed bad about the sheer amount of waste being generated. It would be incredible if this could be used to get rid of scratched up or otherwise unsafe non-stick coatings to the point that the pan is still food safe

EDIT 2: I think they are non-toxic and inert. But I tried to find my source for this and I am failing badly. so deleting this comment

EDIT: I agree they are very waste full since they do not live that long. I have owned three non-stick pans, my cast iron pans have outlived all of them by decades.

Non-stick pans are fine if they are never heated above 500°F (260°C) and never scratched. In general, you probably shouldn't regularly use a nonstick pan for longer than 2 years.

If it is scratched or heated above what it says on the label, then yes it is absolutely toxic.

PFAS (which is what makes nonstick nonstick) have tentative links to several cancers [1]

3M will fight for this patent

Hand sanitizer is also contaminated with other crap... presumably that impacts the adhesive if you're attempting to "recycle" it? I agree, what a weird line.

Assuming it is even ethanol based in the first place, not all. (more than one alcoholic has ended up in the ER thinking all of them are)

It's worth noting that all "forever chemicals" have major health concerns. PFAS, as a class, is the one most studied. They have been explicitly banned in many countries (e.g. France and Sweden) and even some US states (Maine, Minnesota, etc).

But it's a bit like how the DEA has to update their list of banned substances multiple times a month because people keep coming up with new designer drugs and "research chemicals" that aren't technically banned.

I think a broader umbrella term might be POPs (Persistent Organic Pollutants) though that might also be too broad to be useful. A lot of times it's their non-stick properties themselves that make them so toxic, especially to fish and smaller organisms.

Also… Uncure is a popular brand of cyanoacrylate remover. This is already a solved problem it seems.

maybe, but where is the whimsy or delight in that?

Not a lot of whimsy and delight in having your glue joint fail because the delightful & whimsical website gave bad advice.

Dude, people in 2026 still think duct tape is a “great product”.

It’s pretty clear people have no fucking clue what makes a good adhesive.

I’ll settle for just not seeing duct tape in the 10,000 places it doesn’t belong!!
