An environment-friendly fire-retardant coating comprises a coating substrate and fire-extinguishing agent microcapsules which can be ruptured and vaporized to a release fire-extinguishing material to achieve the purposes of cooling and/or fire prevention and/or fire extinguishing upon being exposed to a temperature of not less than 75 C. and/or an open flame environment. In order to break the current situation that the traditional fire-prevention, fire-extinguishing and flame-retardant coatings can only prevent the spread of the fire area, but it is difficult to extinguish the fire sensitively and actively in a short time, there are provided a variety of coatings and/or films which can actively cool down, prevent fire and extinguish the fire, have short response time, have stable fire-extinguishing components in the coatings and/or films, with the films being able to trigger the fire extinguishment repeatedly.

Disclosed is a composition comprising: (A) at least one fluorine-containing ketone; and (B) an effective amount of stabilizer which is selected from at least one of the group consisting of an epoxy compound, a nitro compound, a hindered phenolic compound, a -diketone compound, a phosphite compound, a salicylate compound, a cinnamate compound, a hydroxybenzophenone compound, a hydroxybenzoic acid compound, an alkoxy methane compound, and an organic thio compound. The composition provided by the present invention has stable performance, and can be used as a fire extinguishing agent, a heat transfer medium, etc.

Systems and compositions for suppressing and extinguishing several classes of fire, e.g. Class D, fires are disclosed. The composition includes some form of powdered Aloe vera, a bio-surfactant, a thickening agent, and a diol.
