Intumescent fire retardant coatings are a type of passive fire protection coating that expands when exposed to high temperatures, forming a thick, insulating char layer that helps to protect the underlying substrate from fire damage. These coatings are commonly used in the construction industry to improve the fire resistance of structural elements such as steel beams, columns, and walls.

These coatings are commonly used in the construction industry to improve the fire resistance of structural elements such as steel beams, columns, and walls.
Intumescent fire retardant coatings work by swelling up and forming a protective char layer when exposed to heat, which helps to insulate the substrate and slow down the transfer of heat to the structural element. This delay in heat transfer can help to prevent the structural element from reaching critical temperatures and collapsing during a fire, thereby providing valuable time for occupants to evacuate the building and for firefighters to respond.
These coatings are typically applied to steel structures using spray or brush application methods and can provide fire resistance for a specified period of time, such as 30 minutes, 60 minutes, or 90 minutes, depending on the specific coating and application thickness. Intumescent fire retardant coatings are an important component of fire safety measures in buildings and are often required by building codes and regulations to meet certain fire resistance ratings.
