Used as a combustion catalyst with chlorates, perchlorates and ammonium nitrate where it lowers the ignition points for easier ignition. It does this by "allowing" the oxidizer to decompose at a lower temperature thus releasing its oxygen to support combustion earlier and increasing the burn rate accordingly. A hot water solution is also used to coat Magnesium and other metals to prevent decomposition. No ATFE required to order.
