Buckeye 6% AFFF is an advanced totally synthetic, aqueous film forming foam concentrate. A vapor suppressing aqueous film is formed by the foam solution draining from the expanded foam blanket. It is intended for use at a proportioning rate of 6% (6 parts AFFF concentrate to 94 parts water) on Class B Hydrocarbon type fuels such as gasoline, kerosene and diesel. Buckeye 6% AFFF is not intended for use on fuels which are polar solvent/water miscible such as alcohols, ketones and esters.
