It goes a bit further than that. Cold vulcanization is a 2 chemical process much like epoxy. The fluid has one chemical and the patch has the other. If you use vulcanizing fluid without a patch that has the matching accelerator, the vulcanizing fluid is about the same as rubber cement. Rema is the only system that I can say with certainty that uses the 2 chemical process. Most all of the others are just rubber cement.
