  • Fugitive color fire retardant composition for aerial application
    Patent number: 6395200
    Abstract: In a fugitive color fire retardant composition, the colorant initially colors the composition to a hue which contrasts with the hue of ground vegetation. A non-fugitive component is included in the colorant, in an amount sufficient to provide improved aerial visibility when the composition is first aerially applied to the vegetation. However, the amount of non-fugitive pigment is less than an amount which would prevent the composition from fading after application to an acceptable neutral hue.
    Type: Grant
    Filed: December 18, 2000
    Date of Patent: May 28, 2002
    Assignee: Fire-Trol Holdings, L.L.C.
    Inventors: Robert L. Crouch, Darla D. Burchert
