While also having flame retardant properties, intumescent paint allows steel structures to prolong their stability and strength in the scenario of a fire. By significantly extending the steel failure temperature rate, an extended window of time is created for people to safely evacuate the building and provides firefighters with additional time to control flames.
The special coating increases the Fire Resistance Level (FRL) of a structure. The coating decreases in density and increases in volume in the situation of a fire, while also transforming into an insulating barrier which is significantly larger than the average barriers created by regular paints.
When temperatures increase over 550ºC in the event of a fire, a steel structures load bearing capacity dramatically declines. This makes is essential to meet FRL requirements and provide steel protection though intumescent coatings.
