  • Methods for suppressing flame
    Patent number: 6019177
    Abstract: The invention relates to flame suppression compositions including an inorganic halogen-containing component including bromine, iodine, or a mixture thereof, and an organic binder system having a heat of formation of less than about 200 cal/g, wherein the composition is solid at a temperature below 100.degree. C. and combusts at a temperature between about 160.degree. C. to 1200.degree. C. to produce a plurality of reaction products capable of suppressing a flame upon application thereto and wherein substantially all the halogen is converted to a solid form after suppressing the flame.
