If you can, that would be helpful. I would really like to know the composition of these "vulcanizing fluids", specifically what the cross-linker and activator really are, if indeed they are present. As mentioned by one poster above, normally true vulcanization requires a crosslinker (usually a sulfur compound) and heat (a lot of it) to cause the crosslinking reaction that truly bonds a patch to the base rubber. How do these bike tube patch cements accomplish the same reaction at room temperature.
