KF-CF100 Cable Fire Retardant Coating
KF-CF100 Cable Fireproof Coating is based on waterborne acrylic emulsion and intumescent flame retardant system. Under flame or high temperature, the coating rapidly expands to form a dense char layer that insulates heat and oxygen, preventing flame spread along cables. Oxygen index greater than 45 / Flame retardant V0 grade / Low smoke and non-toxic. Widely used for fire protection coating of power/communication/control/ship cables.
ProductsOverview
Cable Fireproof Coating is a special fireproof coating developed by KeXin New Material. Designed according to GB 14907 and ISO 834 standards, the coating expands in fire to form a dense char layer, effectively blocking heat conduction, buying valuable time for personnel evacuation and fire rescue.
The product has passed national fire protection 3C certification and UL international certification, with fire resistance limit of 1-3 hours. Suitable for steel structures, concrete structures, cables and other buildings and industrial facilities requiring passive fire protection.
Why Choose Cable Fireproof Coating?
CoreAdvantages
Intumescent Flame Retardant · V0 Grade
The coating rapidly expands to 20-30 times its original thickness upon exposure to fire, forming a dense carbonized foam layer. The carbonized layer has a thermal conductivity of only 0.05W/mK, effectively blocking flame heat propagation. Oxygen index greater than 45, flame retardant UL94 V0 grade. According to GB/T18380 cable combustion test, flame does not spread.
Waterborne Eco-friendly · Low Smoke Non-toxic
Waterborne acrylic system, no solvent volatilization during application, VOC less than 50g per liter. The coating does not produce toxic smoke or corrosive gases in flames. Passed IMO FTP Code ship cable fire test and NES713 toxicity index test. Suitable for cable fire protection in enclosed spaces and densely populated areas.
Strong Adhesion · Good Flexibility
The coating has good adhesion to PVC/PE/XLPE/rubber and other cable sheath materials without peeling off. Good flexibility, does not crack when cable bends. Can be applied by brushing/dipping/spraying, adapting to cable bundles of different diameters and shapes. Single coat film thickness 0.5-1mm, multiple coats to achieve fire protection required film thickness.

Frequently AskedFAQ
ApplicationProcess
Surface preparation
Clean substrates thoroughly of oil and rust. Blast steel to Sa2.5. Pre-treat per product spec to keep the substrate clean. Ambient 5-40°C, relative humidity<85%。
Primer / pre-treatment
Select the matching primer or pre-treatment per substrate and system. Mix strictly at the stated ratio and control DFT. Proceed after the primer dries; pre-stripe critical areas.
Main-coat application
Apply the main coat per the process spec, strictly controlling DFT, temperature/humidity and flash-off to keep the film uniform without sagging or pinholes.
Curing process
Cure fully by stoving or by ambient air drying as the product requires. Keep oven temperature uniform within ±5°C and ramp up gradually to avoid coating defects. For ambient-curing grades, ensure adequate ventilation and suitable humidity.
Inspection & acceptance
Inspect all parameters: dry film thickness, adhesion, gloss, colour difference and chemical resistance. Full performance testing is carried out against the relevant standards. Only after everything passes are the test report and warranty issued, and the goods are packed and shipped in dust-free conditions.
