What is intumescent fireproofing?

The intumescent fireproofing coating is a kind of special coating, which is mainly made of polymer as the base material and added with a fireproofing agent, pigment, solvent, and other combinations. Its key components also include a dehydrating agent, carbonizing agent, and foaming agent. When the temperature rises to a certain level, the dehydrating agent will prompt the polyhydroxy compound dehydration carbonization, while the foaming agent decomposes and releases a large number of gases, so that the coating expansion, expansion times up to dozens of times or even dozens of times, to form a dense foam carbonized heat insulation layer. This heat-insulating layer can close the protected substrate, prevent the flame from spreading, and at the same time release the non-flammable gas, dilute the combustible gases released by the heat of the substrate and the oxygen in the foam insulation layer, to effectively isolate the oxygen and heat, to achieve the purpose of fire prevention.

Intumescent fireproofing coating has excellent fireproofing performance and environmental protection performance, is non-toxic and tasteless, harmless to the human body and environment. Its construction is simple, can be brushed, rolled, sprayed and other ways, after construction, the coating dries quickly, the surface is smooth, and has good decorative and weather resistance.

Intumescent fireproof coating is widely used in the coating of buildings, bridges, tunnels, ships, and other fields. In the field of construction, it can be applied to the structure, walls, ceilings, and other parts of the building to provide effective fire protection for the building. In terms of steel structure fire protection, the intumescent fireproof coating can expand at high temperatures to form a protective layer, preventing the steel structure from losing strength and stability in a fire, thus improving the fire resistance of the steel structure.

Overall, intumescent fireproof coating is a kind of fire protection material with superior performance and wide application, which can effectively improve the fire safety of buildings and steel structures.
