The science
How intumescent coatings protect steel.
Under normal conditions, the system appears as a smooth decorative finish. During a fire, it transforms into a thick insulating barrier that delays the steel temperature rise.
01
Before the fire
The steel is coated with intumescent paint. At normal temperatures, it looks like a smooth paint film.
02
Heat exposure
Above approximately 200°C, the coating begins to soften and react to the increasing heat.
03
Intumescent reaction
The coating rapidly expands many times its original thickness, forming a thick insulating char.
04
Steel protection
The char insulates the steel, helping it retain its strength and load-bearing capacity for longer.
