This foam compound is used for rapid action on surface fires.  It produces a foam carpet having good resistance to contamination of hydrocarbons and to dehydration of polar solvents.

It is to be used in 3% concentration on hydrocarbons and at 6% concentration on polar solvents.  The solution are also powerful wetting agents.  They suppress fires in Class A materials move effectively than plain water.

ALCOHOL / POLAR Solvents Resistant Foam on Water Soluble Flammable Liquids forms a cohesive thin polymeric layer ( skin or membrane ) at the interface between  foam and fuel  This thin layer protects the foam and its aqueous film breakdown / destruction of foam by polar solvents.  If the protective layer should become disrupted by agitation, more of the polymeric layer should become disrupted by agitation, more of the polymeric layer is produced by means of regeneration action known as self-handling.  This unique action enables the foam to extinguish and secure effectively; thus providing burnback protection far greater than conventional non AFFF agents. When used on hydrocarbons ( Water insoluble flammable liquids ), ALCOHOL / POLAR Solvent Resistant foam concentrate produces the same rugged aqueous film on fuel surface as a Standard AFFF agent.
