Environmentally responsible Centurion 3% / 6% is the next generation in Alcohol-Resistant Aqueous Film Forming Foam (AR-AFFF). This new formulation demonstrates National Foam's commitment to superior flexibility, firefighting performance, and environmental responsibility. Centurion is used at 3% concentration to extinguish hydrocarbon fires, and 6% for polar-solvent (water-miscible) fires. It is suitable for use with foam compatible dry powder extinguishing agents.
Centurion 3% / 6% is an AR-AFFF concentrate with a special biosynthesized polymer. This polymer is designed to fulfill two functions. The first is to form a protective membrane between the fuel and the foam as it contacts the water-miscible fuel, making extinguishment possible. The second function is to make the foam more stable and heat-resistant, resulting in better burnback resistance and sealability compared to conventional AFFF's. The concentrate formulation is recognized by United States Patents 4,999,119 and 5,207,932.

Mike, we sent this to the vendor and this is their response back;
Lowers water's surface tension allowing it to float on higher tension oil.
It is all synthetic. As long as they keep the pail sealed it is good.
Once they open it, they may want to can it after 10 years.
