Fomtec AFFF 3% -45 is an aqueous film forming foam concentrate (AFFF) with very low freezing point (-45°C) to be used in artic climates. 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% -45 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 premix solution in fresh water.

Opis
Fomtec AFFF 3% -45 is an aqueous film forming foam concentrate (AFFF) with very low freezing point (-45°C) to be used in artic climates.

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.

Application
Fomtec AFFF 3% -45 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% -45 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.
Fire Performance & Foaming
The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Foaming index no less than 7:1 (normally 8:1), 25% drainage time 3.0 minutes (normally 3.5).
Proportioning
Fomtec AFFF 3% -45 can easily be proportioned at the correct dilution using conventional equipment such as:
- Inline inductors
- Balanced pressure, variable flow proportioning systems
- Bladder tanks
- Around the pump proportioning systems
- Water turbine driven foam proportioners
- Self inducting branch pipes and nozzles
The equipment should be designed to the foam type.

Environmental impact
Fomtec AFFF 3% -45 is formulated using raw materials specially selected for their fire performance and their environmental profile. Fomtec AFFF 3% -45 is biodegradable. The handling of spills of concentrate or foam solution should however be undertaken according to local regulations. Normally sewage systems can dispose foam solution based on this type of foam concentrate, but local sewage operators should be consulted in this respect. This product contains NO PFOS or PFOA. Fomtec AFFF 3% -45 is formulated with the latest fluorine technology and uses only “All-C6 fluorinated” compounds.
Full details will be found in the Material Safety Datasheet (MSDS).
Storage / Shelf life
Stored in original unbroken packaging the product will have a long shelf life. The recommended storage temperature range of Fomtec AFFF 3% -45 is from -45°C to 55°C. Freezing and thawing will have no impact on the performance.
Synthetic foam concentrates should only be stored in stainless steel or plastic containers. Since electromagnetic corrosion can occur at joints between different metals when they are in contact with foam concentrate, only one type of metal should be used for pipelines, fittings, pumps, and tanks employed in the storage of foam concentrates. We recommend following our guidelines for storage and handling ensuring favourable storage conditions.
