Abstract: Described herein are liquid fire retardant concentrate compositions comprising mixtures of ammonium phosphate fire retardants. Specifically, liquid fire retardant concentrate compositions comprising one or more of monoammonium phosphate (MAP), diammonium phosphate (DAP), and ammonium polyphosphate (APP) are described herein. The ammonium phosphate fire retardant(s) is typically suspended and/or dissolved in a liquid, typically with the fire retardant(s) incorporated into the composition in powder, or granular form. In certain aspects of the present invention, the compositions provided may exhibit one or more advantages as compared to current liquid concentrate fire retardants, including enhanced strength (i.e., a higher proportion of fire retardant component per unit volume), reduced toxicity, and/or reduced corrosion.

Abstract: The present invention generally relates to fire retardant compositions including one or more carboxylic acids and/or salts thereof, for example, one or more alkali metal salts of a carboxylic acid. In particular, the present invention relates to particulate fire retardant concentrate compositions (e.g., powder compositions) including one or more alkali metal salts of a carboxylic acid. The present invention also relates to methods for preparing the fire retardant compositions described herein.

Abstract: The present invention relates to fire retardant compositions containing at least one carbonate salt, including long-term fire retardant compositions containing at least one carbonate salt and one or more corrosion inhibitors. The fire retardant compositions may be fire retardant concentrate compositions and fire retardant solutions. Compositions of the present invention include solid (e.g., dry) and liquid fire retardant concentrates. Solid fire retardant concentrate compositions include powder fire retardant concentrates (e.g., flowable powder concentrates). Suitable corrosion inhibitors include carboxylic acids (and salts thereof), fatty acids (and salts thereof), water soluble divalent cation compounds, alkali metal phosphates, one or more organic absorption components, and one or more corrosion inhibitor-surfactants. In various embodiments, the fire retardant composition includes one or more of such corrosion inhibitors.

Abstract: The present invention is directed to firefighting foam compositions (e.g., concentrates, foam forming compositions, and solutions) exhibiting improved low temperature stability and/or suitable for use as Class A foams, high expansion foams and in vehicle systems.

Abstract: The present invention is generally directed to fire retardant compositions containing one or more fire retardants, one or more polymers (e.g., one or more biopolymers such as xanthan gum) and colloidal silica. Certain aspects of the present invention are directed to liquid fire retardant concentrate compositions that form a durable (e.g., water-resistant) barrier when applied. The compositions of the present invention optionally include micronized clay. The present invention is also directed to various other compositions, which may be referred to as water-resistant film forming compositions that contain one or more polymers (e.g., one or more biopolymers such as xanthan gum) and colloidal silica. The present invention is also directed to such compositions containing micronized clay and colloidal silica. A water-resistant barrier formed by the compositions of the present invention provide compositions suitable for use in a variety of other applications, in addition to fire retardant compositions.

Abstract: The present invention is directed to magnesium chloride fire retardant compositions, including fire retardant concentrate compositions and fire retardant solutions. In particular, the present invention is directed to solid (e.g., particulate) magnesium chloride concentrate compositions. More particularly, various aspects of the present invention are directed to powder magnesium chloride fire retardant concentrates. The present invention is also directed to methods for preparing magnesium chloride fire retardant solutions from magnesium chloride concentrate compositions of the present invention.
