Fire resistant/Intumescent coatings are paint-like materials that provide fire resistance for buildings from 30 minutes to 2 hours. They are inert at normal temperatures but expand and form an insulating foam barrier at high temperatures of 200-250°C to protect the steel substrate. This coating swells and produces a foam layer when exposed to fire, providing a charred foam barrier of low thermal conductivity to insulate the steel. It can be used on steel, stainless steel, or galvanized substrates to protect them at high temperatures.

Coatings & Benefits

2. Fire resistant/Intumescent coatings are increasingly used all around the world. This is like a paint
material which provide the same finish as that of normal paint. It is widely used in buildings
requiring fire resistance for 30 minutes to 2 hours.
These Intumescent coatings are inert at low temperature and provide insulation at a temperature of
about 200 to 250 degree Celsius. It is designed to insulate the steel substrate, and prevent the
temperature of the steel from rising above the point where it will start to fail.
It is used to protect the steel substrate. This protective layering keeps the properties of steel
unaffected even at higher temperature.

3. This fire resistant coating is perfectly inert at normal temperature. The coating expands at the time
of fire and a chemical reaction takes place which provides an insulating ‘foam like’ barrier which
protects the steel substrate.
This fire resistant coating can also be used with stainless steel and galvanized substrate. However, it
is very important to degrease the galvanization with the primer before applying the Intumescents
coating.

4. Fire resistant coating is an organic paint which is inert at normal temperature

5. It swells and produce a foam type barrier when it is subjected to
high temperature
It provides a charred layer foam of low conductivity
It can be used for buildings with fire resistances up to 2
hours

6. •This coating can be applied by roller, brush or airless spray.
•It can also be applied off-site. This takes the application of fire protection off the critical path and
helps to reduce the overall construction program.
•A range of fully tested topcoats can be specified for use with Intumescent coatings that offer a
wide choice of finish in terms of colour and level of gloss.
•Top coats can easily be repaired and
redecorated.
•Intumescent coatings can be applied onto a galvanised or stainless substrate.
