Abstract
A high performance sealant for repairing punctures in tires includes a highly filtered natural rubber latex, an ultra-fine inorganic powder, a polyamide suspension, and an antifreeze agent that includes water and at least one of ethylene glycol and propylene glycol. The high performance sealant can readily pass through a valve stem of a tire without removing the core and seal, and provides a strong and durable sealing of the puncture.
Claims15
A high performance sealant, comprising:
- about 20% to about 50% by weight of a natural rubber latex;
- about 0.25% to about 10% by weight of an inorganic powder;
- about 0.10% to about 5% by weight of a polyamide suspension;
- about 30% to about 70% by weight of an antifreeze agent including, by weight of the antifreeze agent, 10% to 30% water and a balance of at least one of ethylene glycol and propylene glycol;
- and
- 2% to 8% by weight of a synthetic rubber latex;
- wherein the inorganic powder is selected from the group consisting of calcium carbonate, barium carbonate, titanium dioxide, calcium sulfate, barium sulfate, and aluminum oxide.
A high performance sealant, comprising:
- about 20-50% by weight of a natural rubber latex having an average particle size of about 400 microns or less;
- about 0.25-10% by weight of an inorganic powder having an average particle size of about 150 nanometers or less;
- about 0.10-5.0% by weight of a polyamide suspension;
- about 30-70% by weight of an antifreeze agent including, by weight of the antifreeze agent, 10% to 30% water and a balance of at least one of ethylene glycol and propylene glycol;
- and
- 2% to 8% by weight of a synthetic rubber latex;
- wherein the inorganic powder is selected from the group consisting of calcium carbonate, barium carbonate, titanium dioxide, calcium sulfate, barium sulfate, and aluminum oxide.
