Silca Ultimate Tubeless Sealant V2 has been developed over two-and-a-half years to deliver market-leading sealing performance with exceptional longevity and easy maintenance. Capable of sealing holes up to 6mm, 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. This enables 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. Mechanics will...
