Silca Ultimate Tubeless Sealant

Make punctures a thing of the past with the power of carbon fibre infused sealant. The recycled carbon fibres provide structure to seal the largest punctures while maintaining longevity of endurance specific formulas.

SILCA Ultimate Tubeless Sealant uses the power of a foaming latex formula combined with chopped carbon fibres to boost sealing power even at higher pressures. Ultimate Tubeless Sealant contains 5% by volume, 6, 9, and 12mm chopped carbon fibres which have been reclaimed from recycled bicycles, carbon wheels, race cars, and aircraft components. A unique foaming latex formula allows for the very lightweight carbon fibres to be evenly dispersed within the sealant while riding, which allows for a higher fibre content than possible with Kevlar or fiberglass. At this high fibre loading, bundles of carbon fibre are carried directly to the puncture by the sealant flow where thousands of micro-bubbles collapse on each other, depositing their high stiffness carbon fibres over the hole. During this process, the carbon fibres form a dam of fibres against the tyre casing not unlike a beaver dam of sticks blocking the flow of a stream. This dam of high stiffness/high strength fibres has been shown to seal holes in testing up to 7.5mm, some 25% larger than conventional technologies.
