Leverage The Power Of Recycled Carbon Fiber

SILCA Ultimate Tubeless Sealant uses the power of a foaming latex formula combined with chopped carbon fibers to boost sealing power even at higher pressures. Ultimate Tubeless Sealant contains 5% by volume, 6, 9, and 12mm chopped carbon fibers 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 fibers to be evenly dispersed within the sealant while riding, which allows for a higher fiber content than possible with Kevlar or fiberglass.

Bundles of recycled carbon fiber are carried directly to the puncture by the sealant flow where thousands of micro-bubbles collapse on each other, depositing their high stiffness carbon fibers over the puncture forming a seal. During this process, the carbon fibers form a dam of fibers against the tire casing not unlike a beaver dam of sticks blocking the flow of a stream. This dam of high stiffness/high strength fibers has been shown to seal holes in testing up to 7.5mm, some 25% larger than conventional sealant technologies.

One thing to note is that Silca's Ultimate Sealant must be poured into the tire during tire install. Because of the high carbon fiber content, Ultimate Tubeless Sealant will plug any syringe or valve hole you try to pump it through.

Features:

  • The sealing power of a race-specific formula with the longevity of long-lasting formulas
  • Seals up to 25% larger punctures than conventional sealant technology
  • FiberFoam Technology uses a blend of 6mm, 9mm, and 12mm long carbon fibers which are 400% stiffer than glass fibers with better dispersion through the sealant
  • Effective down to 10°F / -12°C
  • 8oz replacement size
