Fomtec ARC 3×3 is an alcohol resistant aqueous film forming foam concentrate (AFFF-ARC) consisting of a blend of fluorocarbon-, hydrocarbon surfactants and polymers, various solvents and stabilisers. All Fomtec AFFF-ARC foam concentrates are formulated with 100% C6 Pure fluoro-surfactants and fluoro-polymers. On hydrocarbon fuels, Fomtec ARC 3×3 utilises the unique film forming effect to cut off oxygen supply to the fire and the oleophobic properties of the foam enables a stable foam blanket to prevent reignition of the fire. With polar fuels, a polymeric membrane is formed that suppresses vapours and allows the foam blanket to survive on the water miscible fuel surface.

Description
Fomtec ARC 3×3 should be used at a 3% proportioning ratio (3 parts concentrate and 97 parts of water) for both hydro-carbon and polar solvent fuels. May be used with all water types.
For use on Class A type fires, a proportioning ratio of 0,3% to 1% is recommended depending on application and discharge device.
Application
Fomtec ARC 3×3 is tested and approved according to EN 1568 for use on class B hydrocarbon fuel fires such as oil and diesel as well as polar solvent fires such as IPA and acetone. Can also be used on class A fires such as wood, paper, textiles etc. Fomtec ARC 3×3 is also certified for marine applications according to Marine Equipment Directive (MED).
Typical applications include high risk installations such as:
- Storage tanks, process areas and loading racks
- Waste and recycling industry
- Marine vessels and offshore platforms

Fire performance & Foaming
The fire performance of this product has been tested and documented according to the “International Approvals” stated in this document. The use of the product should follow design guidelines appropriate to the type of system and application. The foaming properties are depending on equipment used and other variables such as water and ambient temperatures. Av-erage expansion 6:1, average 25% drainage time 10:00 minutes using UNI 86 test nozzle according to EN 1568-3.
Equipment
Fomtec ARC 3×3 can easily be proportioned at the correct ratio using conventional proportioning equipment.
The equipment should be designed to the foam type. Fomtec ARC 3×3 is suitable for use with Type II (gentle appli- cation) and Type III (direct application) discharge devices as well as sprinklers according to EN 13565-2. It can be used in low and medium expansion applications with all conventional aspirating and non-aspirating discharge devices.
Fomtec ARC 3×3 is also suitable for use in CAF-systems.
Compatability
Fomtec ARC 3×3 can be used together with foam compatible powders and other expanded foams.
It is suitable for all water types.
For mixing with other foam concentrates, contact Fomtec for advise and guidance. For material compatibility please refer to our Fomtec Technical Advices FTA 20 addressing the topic.
Environmental
Fomtec ARC 3×3 is formulated using raw materials specially selected for their fire performance and their environmental profile. All raw materials are registered in the European REACH-database. Fomtec ARC 3×3 is non-toxic, biodegrad-able and each individual component is fully tested and docu-mented.
Fomtec only uses C6 Pure fluoro-surfactants and polymers in our AFFF-ARC formulations. Our film forming (AFFF-ARC) products contains no PFOS or PFOA in accordance with US EPA Stewardship Programme 2010/15 and EU Directive 2017/1000. More details can be found in the Material Safety Datasheet (MSDS).
The products is fully documented to the Norwegian HOCNF regulation, and is registered in the NEMS database.
The disposal of spills of foam concentrate or premix foam solution should be made in accordance with local regulations. For more detailed information please consult our Fomtec Technical Advices FTA 40.
Storage/Shelf life
Stored in original unbroken packaging the product will have a long shelf life. Shelf life in excess of 10 years will be found in temperate climates. As with all foam concentrates, shelf life will be dependent on storage temperatures and conditions. For storage recommendations and material compatibility please refer to our Fomtec Technical Advices FTA 10 addressing the topic.
Inspection/Testing/Maintenance
All foam concentrates should be tested annually. Testing should be carried out by an approved laboratory certified to assess firefighting foam quality according to relevant standards, such as NFPA 11, EN 13565-2, EN 1568 and IMO MSC.1Circ. 1312. Storage containers should be inspected and reevaluated for the suitability of the storage location regarding temperature fluctuations (temperature should be as stable as possible). Exposure to direct sunlight should be avoided.
