Document Type and Number:
WIPO Patent Application WO/2024/050106
Kind Code:
A3
Abstract:
The present invention is generally directed to nanoparticle stabilized firefighting foam concentrates, firefighting foam solutions, and firefighting foams prepared from a concentrate or solution of the present invention containing one or more silica nanoparticles (e.g., surface modified silica nanoparticles) and any or all of one or more components selected from one or more organic solvents, one or more surfactants, one or more biopolymers, and one or more alcohols. The present invention is also directed to methods for increasing the resistance of a firefighting foam to a polar solvent. The present invention is further directed to methods for preparing firefighting foam concentrates including silica nanoparticles (e.g., surface modified silica nanoparticles).
