The Buckeye 3% LT-AFFF is a totally synthetic aqueous film forming foam concentrate for use in cold climates. 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 3% (3 parts LT-AFFF concentrate to 97 parts water) on Class B Hydrocarbon type fuels such as gasoline, kerosene and diesel. Buckeye 3% LT AFFF is not intended for use on fuels which are polar solvent/water miscible such as alcohols, ketones and esters.
