AFFF 3% Foam Concentrate

HD AFFF 3F-C6 Foam concentrates in particular form a thin but strong film on the surface of hydrocarbon fuel, sealing the fuel surface and preventing the release of fuel vapor. The foam spreads rapidly on the fuel surface due to the positive diffusion provided by fluoro surfactants, while the foam blanket excludes oxygen from the fuel surface and provides rapid flame containment and extinguishment. Our AFFF Foam concentrates are intended for use in fresh water, sea/salt or hard water at 3% solution. HD AFFF 3F-C6 is UL Listed and FM Approved.
