Fomtec AFFF 1% Ultra LT is an aqueous film forming foam concentrate (AFFF) consisting of a blend of fluorocarbon-, hydrocarbon surfactants and various solvents and stabilisers. Only C6 Pure fluorosurfactants are used in Fomtec AFFF-formulations. Fomtec AFFF 1% Ultra LT 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 suppress reignition of the fire.
Fomtec AFFF 1% Ultra LT is suited whenever a low pro-portioning ratio, a low freezing point and high fire rating is required. Fomtec AFFF 1% Ultra LT is tested according to EN 1568, UL 162 7th Edition, ULC and FM 5130 for use on class B hydro-carbon fuel fires such as oil, diesel, gasoline and aviation fuels.
The product is also International Civil Organisation (ICAO) level B for use in aircraft rescue and firefighting (ARFF) applications. Fomtec AFFF 1% Ultra LT is effective against class A fires such as wood, paper, textiles etc. Typical applications include high risk installations such as:

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 foams, 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 address-ing the topic. 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, FM 5130 or ICAO.
