A high performance sealant for repairing punctures in tires includes a highly filtered natural rubber latex, an ultra-fine inorganic powder, a polyamide suspension, and an antifreeze agent that includes water and at least one of ethylene glycol and propylene glycol. The high performance sealant can readily pass through a valve stem of a tire without removing the core and seal, and provides a strong and durable sealing of the puncture.

High performance sealant composition for tire repair

An environmentally friendly puncture sealing composition is provided which includes natural rubber latex, suitably high filtered natural rubber latex having a controlled particle size, and an aqueous antifreeze agent that includes water, glycerin and propylene glycol. The aqueous antifreeze agent has a viscosity profile similar to common ethylene glycol-based antifreeze agents, but is free of ethylene glycol. The puncture sealing composition avoids the environmental hazards of ethylene glycol, and is effective at temperatures of &#x2212;30&#xb0; C. and lower.
