Foam Fomtec AFFF
Fomtec AFFF is an aqueous film forming foam concentrate ( AFFF) consisting of fluorocarbon
and hydrocarbon surfactants blended with various solvents, preservatives and stabilizers.

AFFF 3%
Fomtec AFFF 3% is intended for use on class B hydrocarbon
fuel fires such as oil, diesel and aviation fuels. It can be used
with both aspirating and non-aspirating discharge devices.
Fomtec AFFF 3% is especially suited whenever rapid fire
knock-down is essential. It is compatible with all dry chemical
powders and can be used in powder/ foam twin agent systems

Description
Fomtec AFFF 3% is an aqueous film forming foam concentrate
( AFFF) consisting of fluorocarbon and hydrocarbon surfactants
blended with various solvents, preservatives and stabilisers
The foam forms an aqueous film that rapidly cuts off the
oxygen supply and thus knocks down the fire. The expanded
foam from which the film is drained forms a stable blanket that
suppresses the release of flammable vapours and cools down
the fuel surface extinguishing the fire and preventing re-ignition.
The low surface tension of the water foam concentrate
solution enables the aqueous film, although heavier than the
burning liquid, to float on top of the liquid surface.
Fomtec AFFF 3% should be used at 3% proportioned solution
( 3 part concentrate in 97 parts of water) in fresh or seawater.
It may also be stored as a pre mix solution in fresh water.
Application
Fomtec AFFF 3% is intended for use on class B hydrocarbon
fuel fires such as oil, diesel and aviation fuels. It can be used
with both aspirating and non-aspirating discharge devices.
Fomtec AFFF 3% is especially suited whenever rapid fire
knock-down is essential. It is compatible with all dry chemical
powders and can be used in powder/ foam twin agent systems
