Hi Frank, if you're out there, or anyone else who understands chemistry.

Looking at the Shoe Goo MSDS, it's toluene based but that's all I can get
out of the MSDS. The toluene is the solvent which seems to vaporize,
leaving the "glue" behind.

I know about covalent and ionic bonding and the nuclear strong and weak
forces, but common household glue doesn't seem to be any of those.

Common household glues seem to be "mechanical" molecular cantilevered arms.

Do any chemists out there know what "force" is what holds most common glues
together?

I call it the "velcro force" because it's none of the common forces.
But what is it really?
