inflator

Canned tire inflators are single-use devices intended to provide a quick, temporary solution to drivers who experience flat tires. These devices seal the punctured tire and then reinflate it with pressurized gas, providing enough pressure to allow the auto to be driven for a short period at low speed. This allows the motorist to have the damaged tire professionally repaired or replaced, avoiding the need to replace the wheel at the roadside.
Canned tire inflators contain a pressurised fluid mixture of three components:

solvents, which make the sealants adhere to the rubber tire
sealants, which temporarily seal the puncture
propellants, which push the sealant from the can and into the tire and which inflate the tire.
The sealants used in some systems can be removed with soap and water while wet, but require mineral spirits to dissolve them once they have solidified.
