Silca Ultimate Tubeless Sealant with Fibrefoam, 946mL 

SILCA’s Ultimate Tubeless Sealant is an innovative solution to make punctures a thing of the past by using the power of carbon fibre infused sealant.

The product is designed to provide a robust and reliable solution for cyclists who are looking for an easy and effective way to prevent punctures.

The sealant is made with a foaming latex formula which combines with chopped carbon fibres to boost sealing power, even at higher pressures.

The carbon fibres are reclaimed from recycled bicycles, carbon wheels, race cars, and aircraft components, which makes the product eco-friendly.

How does the SILCA Ultimate Tubeless Sealant work?

The sealant contains 5% by volume, 6, 9, and 12mm chopped carbon fibres providing structure to seal the largest punctures while maintaining the longevity of endurance-specific formulas.

The unique foaming latex formula ensures that the lightweight carbon fibres are evenly dispersed within the sealant while riding, allowing for a higher fibre content than possible with Kevlar or fibreglass.

During the puncture sealing process, 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.

This forms a dam of high stiffness/high strength fibres against the tire casing, which has been shown to seal holes in testing up to 7.5mm – 25% larger than conventional technologies.

In summary, SILCA’s Ultimate Tubeless Sealant is a powerful solution that combines the durability and strength of carbon fibres with the sealing power of a foaming latex formula. This product is an eco-friendly choice that can seal even the largest punctures and ensure an uninterrupted ride.

Once the puncture is sealed, the section of the tire will have a carbon fibre reinforced latex area that connects the top and bottom of the hole. This reduces the chances of future punctures in that region compared to other sealant additives such as cornmeal, glitter, or fibreglass.

The superior sealing and hole reinforcement capabilities of carbon fibre allow for a more concentrated level of anti-freeze agents in the sealant, enabling more effective sealing in low-temperature conditions (-7deg C for 6mm holes).

Additionally, the sealant lasts longer (7-9 months, depending on humidity) due to the carbon fibre’s enhanced capabilities.

How often do I need to replenish the sealant?

For optimal performance and to maximise the sealant’s life, we suggest adding replenisher every 90-120 days, depending on the temperature and humidity in your area, to refresh the sealant.
