SEAL's mode of action is based on three components: latex, micro-fibers and BeadBlock™ granules. Synthetic latex liquid (ammonia-free) forms the base in which the microfibres are suspended and BeadBlock granules added. In the 150ml (5oz) size bottle, the BeadBlock granules are pre-added and only have to be added when the 1 liter and 5 liter sizes are used.
On sudden pressure change (when you get a puncture), the liquid rubber quickly solidifies around the hole in the tire. If it does not seal at once, the microfibers will start plugging the hole and in case of a puncture made by an object with a diameter of up to 6mm, the BeadBlock granules will do the rest.
