Unlike gaseous agents, the aerosol does not decompose in the presence of fire nor does it extinguish by oxygen deprivation. Stat-X suppresses fire (primarily) by chemical interference with the “Fire Propagation” radicals (OH, H, and O) that are essential elements in the expansion of the fire. Stat-X interacts rapidly with these free radicals within the fire zone – thus interrupting the on-going fire reaction.
Stat-X aerosol extinguishing agent consists of a patented mixture of a potassium-containing product and an organic binder. After activation, the potassium-containing product decomposes and forms potassium carbonate. The potassium carbonate absorbs heat, causing it to split. This releases a large amount of potassium radicals.
These K radicals react with the free radicals of the fire. The free radicals are the unstable particles that keep the fire going. Stable molecules are formed because the free radicals react with the K radicals. By stabilizing the radicals into molecules, the chain reaction is interrupted.
