Finish Line Tubeless Tire Sealant will not cure inside the tires, therefore, it doesn't need to be refreshed every few months to maintain effectiveness. This sealant will last the entire usable life of the tire. Since there is no liquid latex or ammonia in Finish Line sealant, it is naturally non-toxic, hypoallergenic and safe for carbon fiber rims. Additionally, Finish Line Tubeless Tire Sealant cleans up easily with water – no more scrubbing or scraping cured latex from tires and rims.
FiberLink technology makes this possible. Utilizing DuPont Kevlar fibers, FiberLink seals are extremely robust once they plug a hole. When a puncture happens, fibers rush into the wound and quickly stop air loss. As the tire flexes while it is ridden, the FiberLink mesh tightens and reinforces itself, creating a confidence-inspiring seal that will last ride-after-ride.
