Flame Retardant for Coating
 - NHFR8200



Nitrophor™ NHFR8200  is a kind of novel coating flame retardant based on phosphorus and nitrogen system. It is especially degisned for intumescent flame retardant coating and similar systems like adhesive system, which contains acid source, gas source and carbon source that function through intumescent flame retardant mechanism. 


After flame retarded with NHFR8200, fire proof coating for steel structure can meet all requirements of GB 14907-2002. This fire proof coating has great water-resistance. after taking 120h artificial rain wash, its fire performance still can keep almost the same with that before rain treatment. NHFR8200 also can be used in water-based steel structure fire proof coating and decorated fire proof coating. 


NHFR8200 has advantages like good fire performance, water-resistance, easy to process and great storage stability.
