STUDY ON CHAR EXPANSION AND HEAT SIDELDING OF INTUMESCENT COATING BASED ON INORGANIC FILLERS

Fire Accidents are constant threat to man and materials. When a fire occurs it takes a long time from hours to days to put it off depending on the burning material and other circumstances. This can be reduced in term of risks with the help of findings on Intumescent coating. Traditional fire reta...

description Fire Accidents are constant threat to man and materials. When a fire occurs it takes a long time from hours to days to put it off depending on the burning material and other circumstances. This can be reduced in term of risks with the help of findings on Intumescent coating. Traditional fire retardants are not very effective especially when there is a huge breakout of fires in plants and platforms. These traditional fire retardants also contain halogen and releases toxic vapours thus leading to a severe threat to life and environment. By contrast, intumescent coatings are relatively thin-film products that expand rapidly in a fire to insulate the steel.
