Abstract

A tire sealing and balancing composition comprising:

1. Ethylene Glycol

2. Water

3. Sodium Dichromate

4. Wetting Agents

5. Washed Mica

6. Shore Fiber Asbestos

7. Long Fiber Asbestos

8. A Cellulosic Thickener/Filler.

Claims

1. A tire sealing and balancing composition consisting essentially of:

water;

ethylene glycol in an amount of about 50% by weight of the water;

a corrosion inhibitor;

washed mica;

short fiber asbestos having a length of about 1/4 inch;

long fiber asbestos having a length of about 1/2 inch; and

a cellulosic thickener/filler.

2. The composition of claim 1, wherein the corrosion inhibitor is sodium dichromate.

3. The composition of claim 2, which further comprises a wetting agent.

4. The composition of claim 3, wherein the thickener/filler is selected from the group consisting of hydroxyethyl cellulose, carboxymethyl cellulose and a mixture thereof.

5. The composition of claim 1, wherein the washed mica is present in an amount of about 3 to about 4.5%;

the short fiber and long fiber asbestos are present in an amount of about 2.5 to about 4.5%;

the cellulosic thickener/filler is selected from the group consisting of hydroxyethyl cellulose, carboxymethyl cellulose or a mixture thereof and is used in an amount of about 0.3 to about 1%.

6. A tire sealing and balancing composition consisting essentially of:

water;

ethylene glycol in an amount of about 50% by weight of the water;

sodium dichromate as a corrosion inhibitor;

washed mica having a size of 325 mesh;

short fiber asbestos having a length of about 1/4 inch;

long fiber asbestos having a length of about 1/2 inch;

hydroxy ethyl cellulose, carboxymethyl cellulose or a mixture thereof as a thickener/filler;

a wetting agent;

wherein the washed mica is present in an amount of about 3 to about 4.5%, the short fiber and long fiber asbestos are present in an amount of about 2.5 to about 4.5%; and

the hydroxy ethyl cellulose, carboxymethyl cellulose or a mixture thereof is present in an amount of about 0.3 to about 1%.

7. A tire sealing and balancing composition consisting essentially of the following components at proportions which correspond to the amounts given, ±

5%;

660 gallons of water;

330 gallons of ethylene glycol;

20.5 pounds of sodium dichromate;

6.3 pounds of a wetting agent;

420 pounds of washed mica having a size of 325 mesh;

475 pounds of short fiber asbestos having a size of about 1/4 inch;

25 pounds of long fiber asbestos having a size of about 1/2 inch; and

52.5 pounds of hydroxy ethyl cellulose, carboxymethyl cellulose or a mixture thereof.

8. The tire sealing and balancing composition of claim 7, wherein all components are present in an amount of ±

2% of the recited proportions.
