AQUEOUS FIRE-FIGHTING FOAMS WITH REDUCED FLUORINE CONTENT

摘要

Aqueous film forming firefighting composition concentrates are provided that contain an effective amount of a monomelic zwitterionic or anionic C6 perfluoroalkyl surfactant having a molecule weight less than 800 daitons. The compositions also contain an effective amount of a foam stabilizing agent, and an effective amount of at least one non-fluorinated surfactant. The composition has less than 0.8 % F, and is substantially free of any surfactant containing a perfluoroalkyl group containing more than 6 carbon atoms. The composition meets Military Specification MIL-F- 24385F.
