Its hybrid natural and synthetic latex formula provides a long-lasting, injectable solution for clean and efficient top-ups. Silca's sealant utilises Fiberfoam technology, incorporating small carbon fibre strands that are 400% stiffer than fibreglass, enabling punctures to be plugged rapidly with minimal air loss. The latest formula remains liquid for up to six months, drying more slowly while maintaining its superior sealing power. Adjustments to the carbon strand length have improved injectability without compromising performance. The formula is also CO2 safe, ensuring it stays effective and does not coagulate during inflation. The carbon fibre-reinforced seal forms a strong, airtight barrier, performing reliably even in extreme temperatures as low as -15°C.
This guide is for cyclists looking to maintain optimal tyre performance with Silca Ultimate Tubeless Sealant V2. The sealant offers market-leading sealing capabilities, ensuring a reliable and long-lasting solution against punctures. A key benefit is the Fiberfoam technology, which quickly seals holes up to 6mm. Note that while the sealant is designed for longevity, regular checks and top-ups are still recommended for peak performance.

Troubleshooting
Sealant isn't sealing punctures effectively.
Check sealant level; add more if low. Ensure tyre pressure is correct. Inspect the tyre for larger punctures that may exceed the sealant's capacity.
Sealant is leaking from the tyre.
Check valve stem for leaks; tighten or replace the valve core. Ensure the tyre is properly seated on the rim. Inspect the tyre for cuts or damage.
Sealant appears to be drying out quickly.
Check storage conditions. Ensure the sealant is not exposed to extreme temperatures or direct sunlight. If the sealant is older than 6 months, consider replacing it.
Difficulty injecting sealant through the valve stem.
Ensure the valve core is removed. Use a sealant injector with a narrow tip. Agitate the sealant bottle before injecting.
