Provided are self-binding suspensions and coated substrates prepared using self-binding suspensions. Also provided are methods of preparing self-binding suspensions. Methods may include preparing a binder solution; preparing a titanium dioxide-zinc oxide suspension using ultrasonication; mixing the binder solution with the titanium dioxide-zinc oxide suspension and a surfactant to form a self-binding suspension composition; and coating a glass substrate with the self-binding suspension composition to form a coated glass substrate.

The presently claimed invention relates to polyalkyleneimine-based polymers that are useful as dispersants and a process for the preparation thereof. The presently claimed invention is also directed to dispersants that are useful in solvent-based dispersion systems as well as in water-based dispersion systems.

An aqueous composition, which can be diluted with an aqueous diluent to provide a foam precursor composition, is provided. The foam precursor composition can be aerated to form a firefighting foam. The present aqueous firefighting compositions include a surfactant mixture containing a siloxane-based surfactant together with one or more of a nonionic surfactant, an anionic surfactant, and a zwitterionic surfactant. The aqueous firefighting compositions also include a polysaccharide thickener and an organic solvent, such as an alkylene glycol, glycerol and/or a glycol ether.
