On further investigation it seems that some bicycle tire tube patch
adhesives may indeed contain rubber vulcanization accelerators. For
example the MSDS(Material Data Safety Sheet) for REMA Tip Top
Vulcanizing Fluid CFC Free indicates that it contains 1.0 – 2.5 %Wt of
N-Ethylcyclohexylamine, an amine having a number of commercial
applications including use in rubber formulations. The general
mechanism of tube patch adhesion remains, I believe, as indicated
above.

So, bottom line what are the recommended glues?

I don't use patch kits, I've always just used a piece of tube to
patch. Patch kits always seemed like a very expensive way to get a
very small tube of cement and some precut rubber in a small box.

What's a suggested glue for tube on tube patching?

I do not use old butyl rubber tubes for patches.
I use high solvent concentration glue and Rema patches.
