Low Viscosity Polar-Solvent Fire-Fighting Foam Compositions

View page
US Patent:
54964750, Mar 5, 1996
Filed:
Oct 30, 1992
Appl. No.:
7/969622
Inventors:
Chang H. Jho - Dobbs Ferry NY
Yung Loh - Woodside NY
Karl F. Mueller - New York NY
Assignee:
Ciba-Geigy Corporation - Tarrytown NY
International Classification:
A62D 100
A62D 102
US Classification:
252 2
Abstract:
Low viscosity, concentrated aqueous solutions of polysaccharide gums are prepared using certain water-soluble, anionic copolymers as viscosity reducers. These low viscosity polysaccharide gum solutions are used in the formulation of low viscosity polar-solvent fire-fighting foam compositions, especially "3. times. 3" ("three by three") concentrates. The low viscosity compositions of the present invention are found to have exceptional stability as well as significantly improved fire-fighting performance.
