  • the first surfactants enable the independent formation of a closed water film on the surface of the fire material (e.g. fuel): As a vapor barrier, this water film hinders the transition of the flammable liquid into the gas phase and thus minimizes the fire material maintaining the fire or being explosive / explosive Forms gas mixtures.
