Flame Retardant for Steel Structure
 - NHFR8202



Nitrophor NHFR8202 is especially developed for intumescent flame retardant coating and similar systems like adhesive system, with acid source, gas source and carbon source 

NHFR8202 takes effect through intumescent flame retardant mechanism. 


Flame retarded with NHFR8202, 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. 


NHFR8202 also can be used in water-based steel structure fire proof coating and decorated fire proof coating. 


Compared with NHFR8200, it has a lower price and a higher cost performance.
