Elmers Glue + Super glue =?????

i was making some stamp glue where i mixed some Elmer glue and vinegar. but wanted to see Wat happens when i mix Elmer's glue, vinegar, and super glue. like in 10 seconds the solution turned into a rubbery solid which took the form of the container. can any body tell me why this happened. it held its shape and slightly reminded me of molding silicone. it wasn't sticky and came out of the plastic cup easily.

I repair my ceramic that's cracked, chipped and even a small break say where a piece is gone like the end of a plate or atop of a mug using crazy glue and baking soda and to make it even and smooth I use fine sandpaper . You put glue on the chip no matter how big use common sense the bigger the chip the more glue and it can be layered put the glue and baking soda on top do not mix it together it hardens on contact it mimics ceramic immediately. It will save you tons of money if you are a collector of dishes or anything ceramic it works on more than dishes I've used it on countless things and nobody can tell. You also might want to buy a paint kit from a store like "Michael's" it's best to get a primary colors paint set along with black and white paint. You can also just buy the individual bottles but it's cheaper to buy the set that way and you can make any color you want no matter what it is because pre-made colors have a very small chance of matching perfectly. Also to cure the paint if needed "I recommend curing it" get "mod podge" which can run from like $7 and up However I found it at Dollar Tree last week I bought the entire shelf of 20 I also recommend doing that if you find it cause I don't think it's something that's always there. After sanding your item use the paint to cover the white sanded area even if it's white whatever you repaired that way it matches perfect like nothing happened remember to buy the primary color paint set w/ black and white or buy them in the little single bottle but I'm sure the sets are cheaper and the same size bottle. That way you can make your own color no matter what it may be!

As for breaks layer it by putting it on and wait about 5 seconds to dry then put the glue again atop where you did so it will build in any direction in layers it will happen very quickly then sand, rinse, dry and paint or if you can't put water on whatever it is your repairing or making then make sure all the powder from sanding and baking soda is off. Use a towel or blow dryer because if not you will see all that powder debris in the paint and it will not be smooth and flawless.

Superglue is Cyanoacrytate. CA hardens if in contact with Water. And since there is a LOT of water in elmers glue, the Superglue would simply harden inside the elmers glue.

. Vinegar (acetic acid) is a solvent for superglue (cyanoacrylate). Elmer's Glue-All is a polyvinly acetate of some sort. Maybe someone else can tell us what all that means.

Bump!

I'll try some of this when the weather is warm and it can be done outside. Superglue fumes can be nasty. Wonder what has been brewed up here.

* Yesterday I saw firsthand the effect of superglue CURING rather than DRYING.*

I had been skeptical of the concept. But it seems to be true.

I was soaking the wood parts of a clothespin in a ziplock bag in order to strengthen the wood. I thought that by sealing the bag immediately, it would allow more time for glue to soak into wood. But in very little time, glue got hot and solidified.

Next experiment: bake a piece of wood to drive off as much moisture as possible, and try again. They say that moisture induces glue to cure. Any bets on cure time?

Well, the good news is this topic shows up first for a "elmer super glue mix" search. You're famous!

From here:

The main ingredient in Super glue is cyanoacrylate (C5H5NO2, for you chemistry buffs). Cyanoacrylate is an acrylic resin that cures (forms its strongest bond) almost instantly. The only trigger it requires is the hydroxyl ions in water...

White glues, such as Elmer's, bond by solvent evaporation. The solvent in Elmer's all-purpose school glue is water. When the water evaporates, the polyvinylacetate latex that has spread into a material's crevices forms a flexible bond. Super glue, on the other hand, undergoes a process called anionic polymerization.

Cyanoacrylate molecules start linking up when they come into contact with water, and they whip around in chains to form a durable plastic mesh. The glue thickens and hardens until the thrashing molecular strands can no longer move.

The super glue is waiting for water to go berserk making long interconnected plastic chains. Elmer's has water, so does the vinegar, super glue went berserk. When the water leaves the Elmer's it gets sticky and wants to grab things, like super glue plastic chains. Mix together, sounds like on the molecular level you made sponge. No idea if the acetic acid helped any, but you could always repeat the experiment substituting the same amount of water for the vinegar. In any case, save the chunk you have, see if it gets harder over a few days as whatever water remains gets out of the Elmer's.

Acetate anhydride is probably not something a regular person can get a hold of, which is what you need to test the effects of vinegar without water on superglue .

That said, Acetate ions can act as hydroxyl ions in some situations, and where you already have an acetate monomer in solution, that would tend to help promote the vinegar to stay in it's hydrogenated form.

My guess is that there's a long, crosslinked polymer occuring. The cyanoacrylate can react with it's self; the vinegar/glue mixture can attach to the amine group on the cyanoacrylate, or directly attack the cyanide group.
As vinegar is an acid and the superglue uses OH- to cure, the vinegar probably slowed the curing process.
Hello, Put super glue on sneakers and it started fuming/smoke like with a powerful scent of super glue. I believe there may have been a substance on the felt strap, before perhaps a glue? as I never had super glue do this. I did breathe some in, and 1 hour later my throat hurt. Next day throat still hurts a little, but I feel fine. Any suggestions? Will I be ok?
I don't know, but I was attaching arrowheads once, and when the glue touched the yarn, the same thing happened once the glue hardened. It got in my eyes, and it's like tear gas!

can you give me the proportions you used when you did this?
