ANSULITE 6% (AFC-3) AFFF (Aqueous Film-Forming Foam) Concentrate is formulated from specialty fluorochemical and hydrocarbon surfactants along with solvents. It is transported and stored as a concentrate to provide ease of use and considerable savings in weight and volume.
It is intended for use as a 6% proportioned solution in fresh, salt or hard water. It may also be used and stored as a 6% premixed solution in fresh or potable water only. The correct proportioning or mixture ratio is 6 parts concentrate to 94 parts water.
Three fire suppressing mechanisms are in effect when using ANSULITE 6% (AFC-3) AFFF Concentrate. First, an aqueous film is formed which works to help prevent the release of fuel vapor. Second, the foam blanket from which the film-forming liquid drains effectively excludes oxygen from the fuel surface. Third, the water content of the foam provides a cooling effect.
