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 space.
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 of concentrate to 94 parts of water.
Three fire extinguishment 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.
