KF – 600

• Water based compound consisting of thermoplastic resins.
• When coated on electrical cables it prevents propagation of fire along horizontal and vertical cable runs.
• It restricts fire propagation caused by internal short circuit and keeps the cable functional for a considerable of amount of time.
• It does not affect the current carrying capacity of the cable, thereby derating not required.
• Mechanically strong, can withstand foot traffic and drop loads.
• HALOGEN / ASBESTOS FREE
• Reduces additional emission of corrosive gases / fumes by suppressing fire.
• No imported inputs.
• Maintenance free.

What stimulates flame spread ?
The primary stimulant for flame spread in cables is called RE-ENTRY HEAT which is heat arising from burning cables that, in turn, pre-heats cables stacked above. This pre-heating cause the cable insulation to degrade and emit flammable fumes that help spread of fire. The RE-ENTRY HEAT is the same stimulant that makes several logs of wood stacked in the fire place burn well.

The second most important stimulant for fire spread is called RADIATIVE FEEDBACK. This is the heat radiating downward from the flame that causes the continued heating and decomposition of the cable insulation.

How Fire Retardant Coating is effective?
Once applied it functions by limiting the oxygen drawn from the atmosphere, thereby inhibiting the combustion and heat build up process in the immediate vicinity of the cable insulation. The coating in turn converts the bunch of cables into one coated cable and effectively compartmentalizes an uncoated fire zone from the coated non fire zone.

Fire Retardant Coating has been proven to be an effective, dependable and economical way to prevent fire spread particularly in cables.

Practical locations where it can be used :

• In vertical and horizontal cable runs, tee-offs, intersections, cable crossings, cable joints etc.
• Where vertical trays pass through grated floors or other floor penetrations where penetration fire seals are not practical.
• Cables in boiler / oil lubricant storage areas, battery rooms and oxygen plants to name a few.
• Cable under false flooring where fixing of penetration seal is not practical.
• Cables affected by coal / lignite dust deposits.
• Cables affected by chemical fumes, acid and hydrocarbons.

Recommendations for Usage :

• By using Fire Retardant Coating / Fire Break, non-fire zones are created along the cable runs to a coated length of 1.2 mtrs. Coating intervals of 5 to 10 mtrs. are recommended for horizontal cable runs.
• Vertical cable runs should be protected by coating the entire length.

Method of usage:

Apply two to three coats by brush only of Fire Retardant Coating KF-600 at intervals of 2 to 3 hours to achieve a DFT of 2 mm.
