Tire sealant and tire repair kit
An object of the present invention is to provide a tire sealant having excellent injectability and a tire repair kit. The present invention relates to a tire sealant containing a natural rubber latex; a synthetic resin emulsion; an anti-freezing agent; and phosphate ions or acetate ions; wherein the content of the phosphate ions is from 4.5×10 −3 to 11.0×10 −3 mass %; the content of the acetate ions is from 0.05 to 0.2 mass %; and the relative dielectric constant of the tire sealant is not less than 52.9; and a tire repair kit using the tire sealant.
