Abstract
A tire sealer and inflating composition and products made therefrom are described. The tire sealer and inflating composition includes a sealant, a non-flammable propellant with an ozone depletion potential of zero or substantially close to zero, and one or more aromatic hydrocarbons capable of lowering the vapor pressure of the non-flammable propellant. Moreover, the tire sealer and inflating composition has a vapor pressure less than about 180 psig at 130° F. A preferred propellant is 1,1,1,2-tetrafluoroethane, although other fluorocarbons can also be used. A preferred aromatic hydrocarbon is AROMATIC 150, which is a mixture of aromatic compounds. The tire sealer and inflating composition can either be aqueous or non-aqueous. The disclosed tire sealer and inflating composition is capable of inflating a flat tire or other inflatable objects and seal a puncture wound.
