Fomtec AFFF 3% -45 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 3% -45 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 3% -45 should be used at 3% proportioning (3 part concentrate and 97 parts of water). May be used with all water types. Fomtec AFFF 3% -45 can be stored as premix when blended with fresh water. For use on Class A type fires, induction ratio of 0,3% to 1% is recommended depending on application and discharge device.
Fomtec AFFF 3% -45 can be used together with foam compatible powders and other expanded foams. It is suited for all water types. For mixing with other concentrates, contact Fomtec for advise and guidance. For material compatibility please refer to our Fomtec Technical Advices FTA 20 addressing the topic.
