Abstract
A new tire sealant and inflator composition is provided, which combines a sealant in an aqueous carrier with a non-flammable, non-ozone depleting propellant/inflator. A preferred composition combines a sealant composition with 1,1,1,2-tetrafluoroethane (134a). In a preferred embodiment, a vapor pressure depressant is combined with the sealant and 134a. A preferred sealant and inflator composition comprises from about 20% to about 80% of 134a, from about 2% to about 10% of a sealer, such as latex, or a polyvinyl acetate emulsion; from about 1% to about 8% of a freezing point depressant, such as an alkylene glycol; from about 0.1% to about 1% of a corrosion inhibitor, such as ammonia; from about 30% to about 70% of a carrier, such as water; and from about 4% to about 40% of a vapor pressure depressant, such as a glycol ether. A preferred vapor pressure depressant is 2-butoxyethanol, and a preferred freezing point depressant is ethylene glycol. Preferably the sealant composition combine with 134a or other non-flammable and non-ozone depleting propellant/inflator is biodegradable.

14. A method for inflating inflatable objects formed with rubber, such as tires, said inflatable objects having input ports for allowing inflation thereof, comprising the steps of:
-
providing a container having therein a pressurized mixture of a sealant and a non-flammable propellant/inflator, said propellant/inflator having an ozone depletion potential of zero and said sealant capable of sealing openings in said inflatable objects upon contact with air, said pressure in said container being sufficient to liquify said propellant/inflator at ambient temperatures, and said container having a discharge port with a valve for regulating fluid flow through said discharge port; engaging said discharge port of said container with the input port of an inflatable object, the pressure inside of said inflatable object being less than the pressure in said container; and actuating said valve to allow fluid communication between said container and said inflatable object, the temperature and said pressure in said inflatable object being such that said liquified propellant/inflator is transformed into the gaseous state with the resultant expansion of the gas formed thereby being sufficient to both propel at least some of said sealant and propellant/inflator into said inflatable object and to at least partially inflate said object. - View Dependent Claims (16)
