The definition and classification of Fire-Resistant Coating

Fire-Resistant Coating is a commonly used material for economic and effective fire prevention. The composition of fireproof paint includes flame retardant compounds such as rice husk, acrylic, epoxy, and other special chemical additives and chemicals. After painting the materials that need to be fireproof, which are iron, steel, and fireproof paint, they will form a protective layer that helps the steel structure avoid harmful effects when exposed to fire for a long time.

Fire-Resistant Coating for steel structures includes two types:

Intumescent:

    Advantages: 1. Expands many times thickness when heated, creating a heat-insulating char layer (1–4 hours fire resistance).

                         2. Thin application (0.5–2mm), lightweight, and aesthetically suitable for indoor use.

                         3. Eco-friendly (water-based, low VOC).

    Best for: Commercial buildings, cables, decorative structures.

Non-Intumescent:

    Advantages: 1. Inorganic materials with excellent weather resistance (ideal for outdoor/harsh environments).

                         2. Long lifespan (15–20 years), withstands >1200°C temperatures.

                         3. Cost-effective for large-scale projects.

    Best for: Tunnels, industrial plants, bridges.

Choosing Tips:

Need lightweight + high fire resistance? → Intumescent.

Need durability + low cost + thick protection? → Non-Intumescent.

Benefits of using Fire-Resistant Coating for steel structures at construction sites:

The outstanding feature of fireproofing paint for steel structures is maximum heat resistance up to 1000℃. The paint’s fire resistance can last up to1-3 hours or more (depending on the type of paint). The high heat resistance of fire retardant paint helps to keep the steel structures unaffected, limiting casualties and damage. This property also helps slow the spread of fire and prolong the time it takes to put out the fire.

In addition to ensuring safety for people and property, fireproof paint also limits the amount of toxic gas released from the fire. This makes the firefighting work more convenient and less dangerous. And yet, this passive fire protection material is easy to apply and does not take much time to construct.

The range of applications of Fire-Resistant Coating for steel structures:

Thanks to the composition of epoxy resin, flame retardant Poly Phosphor, organic solvents, and insulation foam, fireproofing paint can slow down the heat exposure of steel structures in the event of a fire incident. Therefore, this paint is widely applied in many industries such as petroleum, petrochemical, Cable, power plant, and construction. In addition to steel structures, fireproof paint can be applied flexibly on other materials such as concrete, wood, etc.

In addition to steel structures, fire retardant paint can be used for many other materials such as concrete, wood, etc. No matter what surface is covered, fireproofing paint can still perform well the function of fire and surface protection.
