Abstract
A tire sealant and inflator composition for the repair of puncture wounds in pneumatic tires and the like. The composition utilizes a sealing component consisting of an acrylic resin dissolved in a suitable solvent and a hydrochlorofluorocarbon and/or hydrofluorocarbon propellant component to deliver the sealing component from an aerosol container into the tire to a driveable state.
Claims30
An anhydrous, essentially nonflammable sealant and inflator composition for introduction into an interior of a pneumatic tire through a valve stem, comprising:
- 10 to 90 weight percent of a propellant;
- 90 to 10 weight percent of a solvent;
- and
- 0.1 to 30 weight percent of a one part air dryable thermoplastic acrylic resin selected from the group consisting of an acrylic acid polymer, an acrylic acid copolymer, a methacrylic acid polymer, a methacrylic acid copolymer and ester derivatives thereof, substantially dissolved in said solvent, said resin forming a continuous coating on an interior surface of a tire cavity about a puncture in said tire, through non-foaming evaporation of said solvent and rotation of said tire.
An anhydrous, essentially nonflammable sealant and inflator composition for introduction into an interior of a pneumatic tire through a valve stem, comprising:
- 20 to 60 weight percent of a propellant;
- 75 to 20 weight percent of a solvent;
- and
- 1 to 20 weight percent of a one part air dryable thermoplastic acrylic resin selected from the group consisting of an acrylic acid polymer, an acrylic acid copolymer, a methacrylic acid polymer, a methacrylic acid copolymer and ester derivatives thereof, substantially dissolved in said solvent, said resin forming a continuous coating on an interior surface of a tire cavity about a puncture in said tire, through non-foaming evaporation of said solvent and rotation of said tire.
As an article of manufacture, an aerosol container comprising a sealant and an inflator composition comprising:
- 1 to 20 weight percent of a one part air dryable acrylic resin selected from the group consisting of an acrylic acid polymer, an acrylic acid copolymer, a methacrylic acid polymer, a methacrylic acid copolymer and ester derivatives thereof;
- 20 to 75 weight percent of a solvent;
- and
- 20 to 60 weight of a propellant giving said aerosol container an initial pressure ranging from about 20 to 110 pounds per square inch gauge, measured at 70 degrees Fahrenheit, thereby permitting a user to seal a pneumatic tire by the application of said sealant to an interior of said tire through a valve stem on said tire.
