KF-FR100 Intumescent Fire Retardant Paint
KF-FR100 intumescent fireproof coating uses APP/PER/MEL as the P-C-N intumescent flame retardant system. When exposed to fire, the coating expands 50-80 times to form a carbonized insulating layer that keeps the substrate temperature below the critical value. It is widely used for fire protection of combustible substrates such as wood/cables/plastics and steel structures.
ProductsOverview
Intumescent 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 a fire to form a dense carbonized layer, effectively blocking heat conduction and 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 intumescent fire-retardant coatings?
CoreAdvantages
P-C-N Intumescent Flame Retardant System
A classic intumescent flame retardant system of ammonium polyphosphate (APP/acid source) + pentaerythritol (PER/carbon source) + melamine (MEL/gas source). When exposed to fire, APP releases phosphoric acid to catalyze PER dehydration into char, and MEL releases inert gas to expand the carbon layer, forming a thermal conductivity<0.1W/(mK)的Thermal Insulation层。
Fire protection across multiple substrates
Combustible building materials such as wood/plywood/density board. Fire protection for cables/cable trays. Steel structures (in combination with epoxy fireproof coating). Fire protection for plastic pipes and plastic products. Fireproof coating for tunnels and underground spaces.
Finishing Fire Protection · Both Aesthetics and Safety
Water-based intumescent fireproof coating forms a smooth white or color-adjustable coating after drying. Water-based topcoat can be applied for decoration without affecting fire performance. Suitable for indoor wooden structures and public spaces that require both fire protection and decorative effects.
Professional coating technology support services
Kexin has an experienced coatings R&D and applications team that supports the whole process - substrate analysis, coating selection, optimisation of process parameters and on-site application guidance. Our engineers commission the coating parameters on your own production line so that finish quality and output are both optimised.
Eco-compliant green manufacturing system
All products are RoHS/REACH compliant and their VOC content meets national environmental standards. Waterborne and high-solids low-VOC formulations are continuously refined to keep pace with ever stricter environmental requirements. Environmental performance test reports issued by third-party authorities such as SGS and CTI are available on request.
Complete quality control and batch traceability
A quality-control system covering the whole process, from incoming raw materials to finished-goods dispatch. Every batch undergoes rigorous physico-chemical testing and simulated application trials. Batch numbers are traceable end to end, so raw-material sources and production data can be retrieved. Each shipment is released with a batch test report and a product warranty, so customers can use it with confidence.

Frequently AskedFAQ
ApplicationProcess
Surface preparation
Thoroughly clean the substrate to remove oil, rust, and oxide scale. Sandblast steel to Sa2.5 grade. Perform surface pretreatment according to product requirements to ensure the substrate is clean. Ambient temperature 5-40°C, relative humidity<85%。
Primer application
Select the primer matched to the coating system and substrate. Mix strictly at the product ratio and control film thickness. Proceed to the next step after the primer dries. Pre-apply reinforcement at critical areas.
Main-coat application
Carry out the main coating application according to process requirements. Strictly control construction parameters such as film thickness/environmental temperature and humidity/flash-off time. Ensure the coating is uniform and consistent with no sagging or pinholes. Manually pre-coat complex areas to ensure full coverage.
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 DFT, adhesion, gloss, colour deviation and chemical resistance against the relevant standards; issue test report and warranty after full pass, then pack in clean-room conditions.
