Passive Fire Protection Coatings
Fire protection is important for:
Fire strikes when least 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, immeasurable damage to the safety of people and properties.The fire can start from external source or internal source, just from anywhere and without warning. Fire takes advantage of unprotected surfaces and areas 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 material goods, but there are fewthings that money simply cannot replace. The conventional paints coated over structural steel, concrete and wooden 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 people and limiting theamount of structural damage.There is no second chance with the fire. Onehas todoit right first time.
How Monarch’s FlameGuard coating protects in the event of fire?
Monarch's FlameGuard fire retardant intumescent coatings offer 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 plywood and OSB etc.,
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 low conductivity 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 the heat 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 free and resist cracking or crumbling.
Active Fire Protection Vs Passive Fire Protection
Active Fire Protection
Methods that require a certain amount of motion and response in order to react to put out the fire by locating smoke, % ames or heat, eg. Smoke & Heat extraction systems, Sprinkler systems, Fire extinguisher systems, Gaseous cleanagents, Fire$ ghting foam.
Passive fire protection
Methods that contain, minimize the impact, or slow the spread of the fire. Contrary to active $ re protection the coating system becomes an integral element of structural $ re protection and fire safety in buildings within a specified fire compartment aswell as ensuring that the load bearing capacity of the fire exposed structure is not reaching a critical level, the passive type does not need a response before reacting tothe fire eg. Intumescent coatings, Retardant coatings, Resistive coatings, Ablative coatings.
