Tire sealant composition
First Claim
1. A tire sealant composition for injection into pneumatic tires, comprising:
- about 1 oz. (by weight) of sodium polyacrylate;
about 37 oz. (by weight) of asbestos fibers;
about 300 oz. (by weight) of ethylene glycol;
about 8 oz. (by weight) hydrocarbon process oil;
about 5 oz. (by weight) of detergent as a wetting agent and emulsifier;
about 27 oz. (by weight) of sodium bicarbonate; and
together with sufficient water to yield about 4.5 gallons (imperial measure) of final product.

Abstract
A tire sealant composition for injection into pneumatic tires is provided. The tire sealant composition promotes heat transfer in a rolling tire, thereby keeping the tire somewhat cooler; it assists in balancing the wheel and tire, thereby prolonging the life of the tire and precluding unnecessary unevenness of wear of the tire; and the tire sealant composition serves to seal the tire around the wheel rim and particularly in the tread area of the tire against punctures. The composition includes a thickener and binding agent, asbestos fibers, ethylene glycol, hydrocarbon process oil, a detergent as a wetting agent and emulsifier, sodium bicarbonate, and water.

8. A process for manufacturing a tire sealant composition to be injected into pneumatic tires, comprising the steps of;
-
(a) mixing water and ethylene glycol together in a mixing vat or drum; (b) starting the continuous mixing action of the vat or drum; (c) adding sodium bicarbonate to the continuously mixing mixture; (d) adding asbestos fiber to the continuously mixing mixture; (e) adding hydrocarbon process oil to the continuously mixing mixture; (f) adding detergent to the continuously mixing mixture; (g) testing the pH of the continuously mixing mixture and adjusting the pH to about 8.0 or 9.0 by the addition of suitable buffers or acidifiers, as necessary; (h) pre-mixing the thickener and binding agent sodium polyacrylate with water; (i) adding the pre-mix of step (h) to the continuously mixing mixture; and (j) continuing the mixing action of the vat or drum until the composition is thoroughly mixed. - View Dependent Claims (9, 10)
