Nagging question: is "vulcanizing fluid" just plain old rubber cement?

I agree with you but want to point out that the sticky surface on the patch is not exactly a glue. It contributes to the bond by supplying the vulcanizing chemicals to the mix. The natural rubber in the cement is what becomes the real adhesive when activated by the vulcanizing chemicals. Then it chemically attaches to both the patch and the tube effectively bonding the patch to the tube.
I don't know why this bugs me since I've had one flat to patch in the last 6 or 8 thousand miles, but for some reason I want to buy a lifetime supply of cement and bulk package of patches, and the cement has to be the "real" thing.

But is the rock hard stuff inside vulcanized or not? Now I'm thinking it must be since just rubber would be softer ... unless they mix in some sort of actual glue. The unknowns are frustrating.

Wait, we know that vulcanizing chemicals are on the patch? Then why/how could they be in the fluid to begin with? The fluid would just be rubber in solvent, with maybe some accelerant.

I spent hours one night looking for a way to reliably carry true vulcanizing fluid in tiny reusable tubes, so I could make use of the incredible volume deal on rema patches.
E.g. sample perfume vials.

The Park flat kits are $3 each, so I just spend the $12 and replace the glue tubes in my repair kits as needed.
I do have quite a few extra patches, though.

I don't know the answer, but this is what I use. The little tubes dry up way too quickly.

Kit doesn't match
I buy patches in bulk and have yet to buy small tubes in bulk, but I have had this lot of 10 tubes for $10 (shipped) in my ebay watch list for months:
Lot 10pcs Bicycle Tire Tube Patching Glue/Rubber Cement/Adhesive Puncture Repair
There are multiple listing like it, some for less.

No, the vulcanizing reaction is not a free radical process. It has nothing to do with the presence or absence of oxygen. The hardness you are observing has to do with evaporation of the low boiling solvents.

I did the same experiment and found that the Elmer's rubber cement did a very poor job in bonding the patches.

Well, I guess concensus was too much to hope for. I didn't see any difference after about an hour.

I bought a bunch of the little tubes of whatever comes in those little tubes, off Ebay .... no need to worry about buying special sealed containers, and no need to worry about the stuff drying out because if you buy six tubes for three dollars .... that's $20 in flat kits. Another couple bucks for patches and you have a five-ten year supply for five dollars.
However ... for those who cannot tolerate the fact that they cannot figure out why their tubes hold air .... I will gladly sell youo Certified magical Bicyckle Glue Patch Tire Adhesive---straight from Vulcan---and individual patches of Guaranteed Hi-Quality actual rubber-like rubber-compound rubber patch material--also imported from Vulcan---for approximately what it would cost you to buy a new tire and tube.
One cannot put a price tag on Peace of Mind. But I can send you a bill.

Maybe it's actually vulcanizing fluid but it's mislabeled due to a translation error...?

I'm wondering the same thing. Plus, according to Robert's assessment, which seems reasonable to me, it doesn't matter all that much. I'll eventually get some of the cheap tubes of goo, and see how it works for me.

I bought a can of vulcanizing cement, figured it would last me forever.
Like two weeks later my dad sees it and says that he tore a hole in his pool liner. Can he "borrow" my vulcanizing cement to patch it?
Never saw it again.

Would be very interested to see/watch what you are gluing to what and the exact process you are following.
Because I have excellent results w/ Elmers rubber cement, regular tubes, and Park patches.

Like heat gun Idea
I'm repairing an inner tube and I like the heat gun Idea for warming the rubber and assisting the glue in attaching the rubber pieces together...going to give it a whirl...😊

3 pages on rubber cement, TLDR, but I use Slime rubber cement. Came in one of those "standard size rubber cement" canisters, and cost me like $8. I'm sure it will dry up before I use it all, but the times I've used it, it's worked perfectly. Important part is getting the legitimate Rema patches though.
