  • fire retardant compositions have various disadvantages. For example, many fire retardant compositions are detrimental to the physical or mechanical properties of the substrate to which they are applied, for example causing the substrate to loose strength. Often the fire retardant compositions leave an unsightly deposit or residue on the substrate making it less aesthetically attractive. Moreover many fire retardant compositions are acidic and/or corrosive and/or hazardous to humans, which makes them unsafe to handle and limits their applicability.
  • fire retardant compositions comprise halogenated compounds, which are not only unsafe to handle, but can also emit toxic gases in the presence of fire. Toxic gases are frequently more dangerous to humans than the fire itself. Consequently, not only should the fire retardant compositions reduce substantially the flammability of the substrate, but they should also be safe to humans during flaming conditions. It would therefore be desirable to have a fire retardant composition which does not suffer from the disadvantages of the prior art compositions.
