Fire intumescent paint is a type of fire-resistant coating that expands when exposed to high temperatures, forming a layer of insulating char that helps protect the underlying material from the heat of a fire. This type of paint is commonly used in construction to provide passive fire protection for structural steel, wood, and other building materials.

This type of paint is commonly used in construction to provide passive fire protection for structural steel, wood, and other building materials.
The fire prevention principle of intumescent paint is based on its ability to swell and create a protective barrier when exposed to fire. When the paint is subjected to heat, it expands and forms a thick, insulating layer that helps to slow down the transfer of heat to the substrate, thus delaying the onset of structural failure.
Some of the characteristics and advantages of fire intumescent paint include:
1. Fire resistance: It can significantly increase the fire resistance of the treated surfaces, helping to prevent the spread of fire.
2. Aesthetic appeal: Intumescent paint is available in a variety of finishes and colors, allowing it to blend in with the overall design of the building.
3. Durability: It is designed to withstand harsh conditions and provide long-lasting fire protection.
During the construction process, it is important to pay attention to the following:
1. Surface preparation: Proper surface preparation is crucial to ensure adhesion and effectiveness of the intumescent paint. Surfaces should be clean, dry, and free from contaminants.
2. Application method: Follow the manufacturer's guidelines for application, including the correct thickness and number of coats required for the specific fire rating needed.
3. Compatibility: Ensure that the intumescent paint is compatible with the substrate material and any other coatings or treatments that will be used.
4. Maintenance: Regular inspection and maintenance of the intumescent paint are essential to ensure its ongoing effectiveness.
Overall, fire intumescent paint is an important component of passive fire protection in construction, but it is essential to follow proper application and maintenance procedures to ensure its effectiveness.
