Another type of fire-resistive coating is Intumescent paint. Intumescent paints prevents heat transfer to the underlying layers of the steel. Their mode of operation is that when heated at 300 degrees Celsius, they will be bloated and will increase to 20 times the initial thickness. In this case, a charcoal is formed at an approximate thickness of 2 centimeters on the surface, which, while leaving no toxic and harmful gases, itself has the role of insulation and prevents heat transfer to the underlying surface, resulting in the metal reaching the soft temperature Avoid about 600 degrees Celsius. The final surface of this type of anti-fire coating is a smooth surface so that after finishing the coating operation it is not necessary to pave the surface.

Use of this product for internal and external parts of buildings, commercial offices, art galleries, museums, airports, electrical installations, and in particular domestic environments and places where the use of solvent base products or mortar coatings is not possible due to environmental constraints (for examples of hospitals and other closed sites are suggested.)
