## Overview

SILCA Ultimate Tubeless Tire Sealant combines a foaming latex formula with recycled carbon fibers to seal punctures up to 7.5mm and last 7-9 months. Designed for MTB, road, CX, and gravel tires, it offers superior cold-weather performance and eco-conscious materials, all proudly made in the USA.

## Description

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, racecars, 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. At this high fiber loading, 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. 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 technologies. After the puncture is sealed, that area of the tire is left with a zone of carbon fiber reinforced latex bridging the top and bottom of the hole, helping to reduce the likelihood of future punctures in that area when compared to other sealant additives such as cornmeal, glitter, or fiberglass. This superior sealing ability and hole reinforcing ability of the carbon fiber also allows for a higher concentration of anti-freeze agents in the sealant which means more effective sealing at low temperatures (6mm holes seal at 18deg F/ -7deg C), as well as longer lasting sealant (7-9months depending on humidity).

Review: Sealant good price - Great product and excellent reviews elsewhere. Great price at black friday
Review: Excellent Sealant - I've been riding tubeless tires for over a decade on my mountain bikes and about 5 years or so on road and gravel. I've tried all the major brands from Stan's to Orange Seal, etc. While those sealants work well too, I've found myself purchasing this Silca offering exclusively in the last few years because it simply delivers and tends to stay in it's liquid form longer than most. Sealant works very well, especially on tubeless gravel and road tires. Because of the particles in the sealant, this has to be poured into the tire rather than "injected" through the valve stem, otherwise it will likely clog the injector or the valve stem. Because it's Silca, you know the quality is there. The product works very well and would recommend highly.

## Features

- Puncture Protection | SILCA flat tire sealant makes punctures a thing of the past with the power of carbon fiber infused bike tire sealant. The recycled carbon fibers which come from bicycle, racecar, and aircraft components provide structure to seal the largest punctures while maintaining longevity of endurance specific bike sealant.
- The Perfect Sealant | The problem with most tubeless bike tire sealant has been that they work great but dry out quickly, or they can last for a season but don’t plug large holes. We have created a cycling sealant that can finally do both. With a full latex foam sealant combined with performance foam and Carbon Fibers we can finally have a tubeless sealant that lasts for 7-9 months and seals holes 6+mm in diameter.
- Application Process | Starting with a clean, tubeless tire, use the 'pour in' method when installing on a tubeless rim. The quick sealing power makes it impossible to use a syringe or through the valve stem. When we say we can seal a +6mm, we mean it. The key is the carbon fiber that rushes to a puncture or open source and creates a fiber dam coagulant for a extremely effect seal.
- Manufactured In The USA | Silca ultimate bike tire sealant tubeless tires is manufactured in the USA.
