Dr. Eduard Kleiner, President, prior to founding Dynax, was responsible as R+D Director and VP Corporate Research of former Ciba-Geigy Corporation for the development of the Lodyne family of fluorochemical oil and water repellent finishes and fluorochemical surfactants for FX-Agents In 1993, the US Air Force awarded Dynax the SBIR Phase 1AF93-009 research contract to develop an "Improved Formulation of FireFighting Agents for Hydrocarbon Fuel Fires." and in 1994, awarded Dynax the SBIR Phase Il AF93-009 contract which was concluded in April 1996. Dynax was successful developing a class of environmentally more benign AFFF agents, so-called EMB AFFF agents which outperformed the current US MIL-F-24385F AFFF specifications with regard to extinguishment and burnback resistance, while having a 65% lower fluorine content than the leading 3% AFFF agent on the Qualified Product List, 3M's Light Water FC203CF. In 1994, Dynax introduced DX3001, a highly efficient amphoteric fluorochemical surfactant, as well as DX4302, a fluorochemical foam stabilizer, which was replaced in 1995 with the higher efficiency DX5011 foam stabilizer. 3 `The introduction of DX5011 made it possible to produce AR-AFFF and AR-FFFP agents with reduced polysaccharide contents having lower viscosity and improved extinguishment and burnback properties even on the most difficult polar solvent fires, such as acetone fires. In September 2000, Dynax will introduce a next generation foam stabilizer, DX6011, providing improved burback resistance; and in the first quarter 2001, DX4001, a new high efficiency fluorochemical surfactant is scheduled to be introduced. All Dynax fluorochemicals are derived from fluorochemical intermediates produced by the so-called "Telomerization Process," and do not contain any PFOS (Perfluorooctanyl sulfonates) or PFOS derivatives. In addition to its patented fluorochemical surfactants and foam stabilizers for use in FX-Agents, Dynax offers FX-agent producers so-called Dynax Superconcentrates containing fluorochemicals as well as select hydrocarbon surfactants which can readily be converted into FX-agents meeting current US and international specifications. For further information regarding Dynax fluorochemicals for use in FX-agents, please contact: Eduard K.
