Class A foam or also known as “wild fire foam”and “wetting agent”. Intended for use againstClass A fires such as wood, paper, textiles orrubber. Class A foams are blend of surfactantsthat enable strong wetting and foamingproperties. Class A foams are often intended foruse at very low concentration of 0,1 to 1%, andare formulated using environmentally favorableraw materials. In most cases Class A foams arefluorine free foams as well.
