Hilti fire finish 120 cfp sp wb is a high performance water based intumescent fire resistive material or ifrm for architecturally exposed structural steel in interior and exterior applications with approved top coats.
Intumescent paint for steel fire rating.
Flameoff fire barrier paint is an intumescent paint that can be applied to most building materials.
Water based and non toxic this fire retardant fire resistant coating is applied just like standard paints by rolling brushing or spraying and can create a fire rated wall for your structure in as.
Tested to astm e84 and e119 standards for 1 and 2 hours fire rating.
The final decision about required dft fire ratings needed and an amount of product required to achieve needed fire protection of your project is made between your building official and your fire marshall based on thorough review of flameoff full scale fire testing reports from accredited fire laboratories which can be provided to flameoff.
Fire rated designs using thin film intumescent coatings are valid for use in commercial institutional light industrial and residential build ings in canada and the designs tabulated in sds.
The swelling reaction starts usually at about 200 f and the coating can expand up to 50 times its thickness.
Intumescent paints for structural fire protection the most common use for intumescent paint in architecture is to provide an aesthetically pleasing finish on exposed structural steel members.
Thus intumescent paint for steel is a fire barrier coating which in the event of fire forms a non conductive carbon char to insulate the steelwork from the heat and flames.
Exterior intumescent coatings are used in heavy industrial environments or when steel is located on the outside of a building and still needs a fire rating.
Thin film fireproof paint materials that can be used for steel are water or solved based and are typically applied to prevent fires in regular buildings.
Typical spray applied fireproofing provides a thick and spongey surface that requires a finished surround to hide and protect the steel member.
Structural steel is the most commonly protected material but protection can include other materials such as sheet metal sheetrock composite panels and interior woods.
Exterior intumescents also serve well in locations with tight space restrictions like elevator shafts where a thinner alternative option to conventional cementitious fireproofing is desired.
We manufacture an outperforming flameoff fire resistant paint tested to astm e84 and e119 standards and flameoff fire retardant spray tested to nfpa 701 standards.
