Abstract:
Cationic siloxanes in the liquid phase of fire extinguishing foams, with or without other materials as foam promoters, stabilizers or special purpose additives, provide rapid extinguishment of flames, are capable of forming vapor-securing films over burning hydrocarbon liquids to prevent reignition upon foam rupture or disintegration and impart unique elastic properties useful in producing high expansion foams and in producing low expansion foams for sprinkler systems.
Abstract:
Anionic and/or amphoteric siloxanes in the liquid phase of fire extinguishing foams, with or without other materials as foam promoters, stabilizers or special purpose additives, provide rapid extinguishment of flames, form vapor-securing films over the burning hydrocarbon liquid to prevent reignition upon foam rupture or disintegration, and impart compatibility of the foam with dry chemical extinguishing agents.
