Effect of Curing Agent towards Flame Retardancy

5 Effect of Curing Agent towards Flame Retardancy 

The effect of BAPPO in enhancing the flame retardancy was more in the case of phosphorous and siloxane skeletal modified tetrafunctional epoxy systems than that of sulphone-modilied and neat epoxy systems. The improved flame retardancy of siloxane skeletal modified epoxy systems cured with BAPPO maybe due to the synergism between the silox-cuie moiety of epoxy systems cuid phosphorous backbone of BAPPO, leading to VO rating from UL94 test.
