Abstract

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.
