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.

Ate my rim tape and caused failure.
The sealant ate the rim tape and caused failure. Company stated you need to use high tinsel tape? Never had this problem with Stanï¿½s or the Orange stuff.
