SILCA Ultimate Tubeless Sealant with Fibrefoam 946ml (Step1)

INFO

Silca ultimate tubeless sealant with fibrefoam

SILCA's Ultimate Tubeless Sealant is an innovative solution to make punctures a thing of the past by using the power of carbon fiber 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 fibers to boost sealing power, even at higher pressures.

The carbon fibers are reclaimed from recycled bicycles, carbon wheels, racecars, 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 fibers 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 fibers are evenly dispersed within the sealant while riding, allowing for a higher fiber content than possible with Kevlar or fiberglass.

During the puncture sealing process, bundles of 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 hole.

This forms a dam of high stiffness/high strength fibers 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 fibers 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 fiber 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 fiberglass.

The superior sealing and hole reinforcement capabilities of carbon fiber 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 fiber's enhanced capabilities.

How often do I need to replenish the sealant?

For optimal performance and to maximumise 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.

Replenisher can also be used to renew sealant on highly porous tires during initial installation.

When installing some casing tires, the sidewalls may experience weeping, which can reduce the sealant volume by 30% and accelerate the aging of the sealant. By adding 30-50% of the sealant volume with the replenisher, you can ensure the ideal performance and durability. While using CO2 temporarily to seat the tire is possible, it should be released and replaced with a floor pump to preserve the sealant's life.
