<P>PROBLEM TO BE SOLVED: To provide a flat tire sealant that has flowability at low temperature because the viscosity of the sealant is prevented from increasing at low temperature while being excellent in closing properties and maintaining favorable repairability, and is excellent in workability at the injection of a flat tire-sealing agent into a tire. <P>SOLUTION: The flat tire-sealing agent comprises a natural rubber latex, an antifreezing solution, a nonionic surfactant, and a thickener, wherein: the thickener is a urethane-associative thickener; 10 to 30 phr of the nonionic surfactant is contained per 100 pts.mass of a natural rubber latex solid; and 10 to 45 phr of the urethane-associative thickener is contained per 100 pts.mass of the natural rubber latex solid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
