repair - What does vulcanizing solution in patch kits
The cross-links are composed of sulfur atoms, and they act to strengthen the rubber. Vulcanizing solution does not actually vulcanize rubber. What it does is to break the bonds between sulfur atoms in these crosslinks of rubber that has already been vulcanized (for chemists out there, it's a reduction of disulfide bonds).
