TIRE SEALER AND INFLATER COMPOSITION
Disclosed herein is a sealer and inflator composition, comprising: a concentrate; and a propellant/inflator comprising tetrafluoropropene. Also disclosed is a container comprising the sealer and inflator composition as well as a method for using the sealer and inflator composition to inflate an inflatable object.
1 . A sealer and inflator composition, comprising:
a concentrate comprising a polymer emulsion and a carrier; and
a propellant/inflator comprising tetrafluoropropene.
2 . A composition according to claim 1 , wherein said propellant/inflator comprises 1,3,3,3-tetrafluoropropene.
3 . A composition according to claim 1 , wherein said propellant/inflator comprises 1,3,3,3-tetrafluoropropene and 1,1,1,2-tetrafluoroethane.
4 . A composition according to claim 1 , wherein the composition further comprises a vapor pressure depressant.
5 . A composition according to claim 4 , wherein the vapor pressure depressant is present in an amount up to 40 weight percent, based on the total weight of the sealer and inflator composition.
6 . A composition according to claim 1 , wherein the composition further comprises a freezing point depressant.
7 . A composition according to claim 6 , wherein the freezing point depressant is present in an amount up to 25 weight percent, based on the total weight of the sealer and inflator composition.
8 . A composition according to claim 1 , wherein the composition further comprises a corrosion inhibitor.
9 . A composition according to claim 8 , wherein the corrosion inhibitor is present in an amount up to 2 weight percent, based on the total weight of the sealer and inflator composition
10 . A composition according to claim 1 , wherein the propellant/inflator is present in an amount of 20 weight percent to 95 weight percent based on the total weight of the sealer and inflator composition.
11 . A composition according to claim 1 , wherein the polymer emulsion has a solids content of 15 weight percent to 75 weight percent, based on the total weight of the emulsion, and comprises an elastomeric polymer.
12 . A composition according to claim 1 , wherein the polymer emulsion is present in an amount of 3 to 30 weight percent, based on the total weight of the sealer and inflator composition.
13 . A composition according to claim 1 wherein the composition is free of a vapor pressure depressant.
14 . A sealer and inflator composition, comprising:
3 to 30 weight percent of a polymer emulsion,
20 to 80 weight percent of a carrier;
1 to 25 weight percent of a freezing point depressant; and
20 to 95 weight percent of a propellant/inflator comprising tetrafluoropropene, wherein weight percents are based on the total weight of the sealer and inflator composition.
15 . A composition according to claim 14 , wherein the carrier is water.
16 . A composition according to claim 14 , wherein the freezing point depressant is ethylene glycol.
