Abstract
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 −30° C. and lower.
