How does FlatOut™ Tire Additive by MULTI SEAL® work to rapidly seal punctures?
FlatOut™ is a high-tech system of synthetic TangleTek™ fibers (including DuPont™ Kevlar®) and DamRight™ fillers in a carefully designed Never-Settle™ base fluid. When a puncture occurs, the escaping air carries FlatOut to the hole. The TangleTek fibers cling to the side of the puncture and form a “filter” which entraps the DamRight fillers. Together, they form a plug, which seals the leak instantly with almost no air loss. As the tire flexes under load, the fiber/filler mass compresses to form a dense plug. The process will repeat itself for each additional puncture.
NOTE: There is absolutely no drying, curing or chemical reaction taking place. FlatOut™ forms a mechanical/physical plug.
Also, the process is the same whether or not the penetrating object stays in the tire.
