Silca Ultimate Tubeless Sealant with Fibre Foam 236ml

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.

• Effective down to 10F/ -12C
• Seals 7.5mm holes for up to 6 months
• Must be poured into tyre during install
• Not injector compatible - this product seals holes bigger than your valve
• Use Replenisher every 90-120 days for best performance
• 6, 9, and 12mm recycled carbon fibres pieces are dispersed evenly by a foaming latex to create ultra strong seals
• CO2 can be used to seat tyres but should be removed as soon as possible and replaced with air to preserve life of sealant
• Made in the USA
