Abstract : The patent concerns a conventional anti-corrosion paint composition containing a mixture of microspheres some of which contain a foamable plastic material while others contain a spumific material. In the event that a surface coated with this formulation is exposed to heat, the microspheres will melt causing an intermingling of their contents which will produce gas. Such gas causes the other liquids released by the ruptured microspheres to swell and foam creating a non-flammable insulative barrier.
