3. Flame Control Flame Retardant Coatings are designed to meet
federal, state, and local building and fire codes. These coatings retard
the spread of flames and reduce heat penetration through
intumescent technologies. Flame Control Flame Retardant coatings
should be applied when it is necessary or desirous to reduce the
flammability of combustible surfaces.
Flame Control intumescent paints are ideal for a variety of substrates
including wood, sheetrock, metals, fiberglass, composites, concrete,
and open and closed cell foams. Flame Control Flame Retardant
coatings are applied using the same methods as standard latex paints,
and have the same aesthetic appearance as regular paint.

10. Formulation of Fire-Retardant Paints
Coatings are formulated that do not sustain combustion; they should not spread the
flame by rapid combustion nor contribute a significant amount of fuel to the fire.
Fire-retardant coatings are based primarily on chlorinated alkyds,
alumina trihydrate, or a combination of chlorinated paraffins and
antimony trioxide. Flame spread test results depend both on the substrate
and the thickness of the film.
Thermoplastic, organic systems are used as binders:
 Vinyl acetates
 Acrylics
 Epoxies
Active substances are added to these which react
to form an insulating “carbonaceous char” when
exposed to fire.

11. INTUMESCENT
COATINGSThese coatings work by swelling up in the event
of fire and physically creating a barrier between
the steel and the fire for up three hours.
 Fire resistances up to 120 minutes.
 Top coats can easily be repaired and redecorated.
 Can be applied by brush, roller or airless spray.
 Can be applied onto a galvanised or stainless substrate.
Steel loses its structural strength at about 500 C and these coatings
can delay the time it takes to reach this temperature.
How Do Intumescent
Coatings Work?

12. Development of a protective
intumescent layer
When exposed to fire, the intumescent paint expands at temperatures of
between 120 and 200 °C, increases significantly in volume to form a stable,
fine-pore, carbonaceous char. This process is called intumescence.

13. Intumescent coatings prolong the structural life of steel. As
protected steel is less exposed to frequent temperature
variations, its load bearing capacity also increases.
These specialized paints have a wide range of use. They can be
used for steel coatings, wooden coats, or for structural
components like concrete as well. Recently intumescent
fireproofing sprays have been developed that can be applied to
fiber glass structural components, too.
The coatings can be applied off-site as well as on-location.
Off-site fireproofing means there is enough time for workers
to fit, erect, and adjust their structural components. Faster and
easier construction, reduced on-site activities, and ease of
assembly are the major advantages of off-site coating.
Advantageous use of these products can be made in
refurbishment projects. The structural, aesthetic, and
architectural value of the structural objects remains preserved.

14. Demerits of Intumescent Paints and Coatings:
The intumescent fireproofing industry is on the rise and has
already created a stir in the market. However, there are
certain drawbacks associated with these paints.
UV exposure, operational heat, and the humidity of the work
area are three major factors that affect the performance of
intumescents. Intumescents are particularly vulnerable to
environmental exposure at the time of application.
They have a limited fire resistance period. The best
quality, i.e. most expensive, intumescent fire sprays will not
preserve your structural member for more than sixty minutes
or so. As the fire resistance time duration increases, the costs
also increases, and the cost rise is usually exponential
For sodium silicate based intumescent fire sprays, having rubber
or epoxy in the coatings becomes mandatory in order to
promote adherence.

17.  Fire protection coatings do not differ from conventional coatings
thanks to their smooth finish.
Design scope:
Depending on the system used, retrospective enhancement of the
fire rating is possible, as in the case of refurbishment projects.
 Fire protection coatings can be applied in virtually all
environments, even those with particularly high requirements such
as swimming baths and power stations.
 For the coating of interior areas there are especially low-emission
systems that even comply with the high demands required for
sustainability certification.
BENEFITS AT GLANCE
 The coatings, only a few millimetres thick and applied in line
with the profile, emphasize the filigree nature of the structural
steel design.
 Architects have infinite color scope when planning buildings.
Topcoats are available in all RAL or NCS color shades, special
accents can be achieved with DB shades containing micaceous
iron oxide.
Design scope: Flexibility and versatility:

18. CLEANING, MAINTENANCE AND REPAIR
Fire protection coatings can be cleaned very easily. Loose dust and
other contamination can be easily removed by hand or mechanically by
blowing, vacuuming or lightly brushing it off. Oily or greasy
contamination ought to be removed with a sponge or low-pressure water
spray.
Intumescent coatings are resistant to aging and can withstand minor
mechanical stress such as slight bending and temperature expansion
without difficulty. Given correct and professional application and usage,
their service life is virtually unlimited.
Depending on the stress buildings are exposed to, inspections should be
conducted at intervals from 1 year (e.g. industrial buildings) to 5 years
(e.g. museums).
