Passive Fire Protection Coatings:
Fire protection is important for:
- Personnel protection – giving people time to escape or shelter from the effects of the fire Asset
- protection–minimizing damage to the assets before f ire services arriving
Fire strikeswhenleast expected.The speed at which the fire travels or
propagates even a small accidental fire or electric spark caused by
short circuit is sufficient to create huge,
immeasurabledamageto the safety of people and properties.The fire can
start fromexternal source or internal source, just from anywhere and
without warning. Fire takes advantage of unprotected surfacesandareas
concealed fromfire fighters. The consequences - overwhelming heat,
suffocating smoke, loss of time, damage to items of sentimental value
and above all, the loss of life. The insurance company may able to
replace the materialgoods, but there are fewthings thatmoneysimply
cannot replace.
The conventional paints coated over structural steel, concrete
andwooden surfaces are flammable and indeed act as a fuel which aid in
spreading of fire. The intense heat conducted through metal ignites the
paint and combust spontaneously even if not subjected to a flame
directly. In the event, of f ire , the winning time is crucial in
evacuating the
peopleandlimiting theamount of structuraldamage.There isnosecondchance

How Monarch's FlameGuard coating protects in the event of fire?
Monarch's FlameGuard fire retardant intumescent coatings offer
ultimate protection in extensive applications like Industries,
Institutions,
Corporate houses, Show rooms, Residences, Schools, Dormitories, Hospital
Care, Nursing Homes, Hotels, Motels, Retail stores, Restaurants,
Transportation etc., on structural steel, concrete, cables, wood,
rubber, PVC, canvas, gypsum board, polyurethane foam, wooden surfaces,
joists, beams, acoustic tile, rough and finished timbers, open surface
panel board, previously painted wall board, hardwoods, softwoods,
drywall, SPF plywoodandOSBetc.,
This coating after application dries quickly toamatt finish
.Oncontact with fire or excessive heat, the coating puffs up
(intumesces) to several times thicker than original coating film,
forming a sponge - like cellular foam insulating char layer and reduces
available oxygen to the surface. Intumescent is a substance which swells
as a result of
heat exposure, thus increasing in volume, and decreasing in density.An
insulating char of lowthermal conductivity that reduces heat transfer to
substrate and slows the temperature rise of the substrate. The product
works by cutting off oxygen fromthe fuel source inhibiting the
combustion process in the immediate vicinity of the area and reduces
the transmission of fire, heat and smoke to the protected area like fire
retardant jacket during and after exposure to fire. Even after
prolonged exposure to a fire the coating is not destroyed and continue
to shield the substrate by forming lowconductivity carbon char that act
as a barrier between the fire and the substrate. This substantially
decreases the temperature rise, smoke generation and finally insulates
and protects the substrate from theheat of the flame.
The rating of fire retardant coatings depends on the intensity of
the flame, type, coating thickness and other variables.More thickness of
the coatings increases fire protection duration. The coating adheres
tightly and fits to any size and shape of the substrate. It produces
neat, attractive and paintable finish. The coatings are non-toxic,
asbestos freeandresist cracking or crumbling.
