  • Patent number: 10550483
    Abstract: Disclosed are fire-retardant concentrates and solutions comprising mixtures of ammonium phosphates. In certain embodiments, less of the concentrate is needed to form an effective fire-retardant solution. In certain embodiments, the fire-retardant solutions exhibit decreased corrosion, especially with regard to magnesium. In certain embodiments, the fire-retardant solutions exhibit decreased aquatic toxicity.

  • Patent number: 6676858
    Abstract: Colorized fire retardants, and methods of making and using the same, are provided that include an uncolored or minimally colored fire retardant composition and a colorant. The colorant is an aqueous dispersion, slurry, or suspension that includes an insoluble, non-fugitive pigment, e.g., red iron oxide or titanium dioxide. The aqueous dispersion pigment is added to the uncolored or minimally colored fire retardant composition at a time proximate to discharging the retardant onto the fuel. Accordingly, a user has control over the type and amount of colorant added to the fire retardant composition.
