FP-WH Outdoor Non-Intumescent Steel Structure Fireproof Coating
FP-WH is fireproof insulating coating whose main constituent is inorganic material. This coating has strong bonding strength, strong anti-corrosion properties, light coating layer, and the fire-resistant limit up to 3 hours. It is widely applied in steel structure fire protection for large steel structure building, petrochemical industry, commercial building, electric power, workshop and warehouse to improve fire- resistant duration, which can satisfy the fire protection requirements.
FP-WH is water-based thick fireproof coating for steel structure that provides fire protection for steel structure load-bearing component. After spraying and painting this coating on the surface of steel structure, it will form insulating layer relying on the coating's own incombustibility and low thermal conductivity once gets on fire, and reduce the direct damage to the load-bearing component.
Product advantages:
Not contain asbestos and organic solvents;
No excitant odour;
Non-toxic and environmentally friendly;
Light coating, good bonding performance, high strength, and superior anti-corrosion performance;
Excellent fire and weather resistance.
