ABSTRACT:
A low density, epoxy-based intumescent fire resistive coating, having a density below about 1.10 grams/cc, and most preferably below about 1.0 grams/cc, and a method for forming the same, are disclosed. This method includes the steps of forming an epoxy-based intumescent mastic, having minute particles of amorphous silica dispersed therein. The mastic is then sprayed in droplets on at least one surface of a substrate to form a low density mastic coating on the surface. The low density mastic coating then cures to form a low density, intumescent fire resistive coating. Preferably, the method of invention further includes the step of dispersing at least one type of gas within the mastic, or within at least one part of the mastic to further reduce the density of the cured intumescent coating.
