Intumescent coatings

Intumescent coatings can be in forms of thin and thick film. When exposed to fire, the coatings will swell to many times their original thickness with the resultant char insulating the underlying steel substrate. Most coatings are applied in situ and are suitable for interior/exterior exposure. However, the use of off-site application is increasing. The coating systems offer reasonable resistance to mechanical damage and any damage can be easily repaired.
