## Abstract

A tire sealant composition, comprising: latex emulsion, surfactant, anti-freezing agent, dendrimer, and water, and optional component(s) selected from the group consisting of wetting agent and porous particles. The tire sealant compositions are excellent in high temperature stability and/or long term stability.

## Claims

### Claim 1

A tire sealant composition, comprising: latex emulsion, surfactant, anti-freezing agent, dendrimer, and water, and optional component(s) selected from the group consisting of wetting agent and porous particles,
wherein the weight percentage of anti-freezing agent in the sealant composition is ranged from 20 wt % to 95 wt %;
wherein the weight percentage of latex emulsion in the sealant composition is ranged from 0.01 wt % to 20 wt %;
wherein the weight percentage of dendrimer in the sealant composition is ranged from 50 ppm to 40000 ppm;
wherein the weight percentage of the surfactant in the sealant composition is ranged from 0.1 wt % to 10 wt. %; and
wherein the dendrimer includes dendrimer with succinamic acid surface, dendrimer with carboxylate sodium salt surface, dendrimer with primary amine surface, or a combination thereof.

### Claim 2 (depends on 1)
