Fireproofing paint for steel structures is a widely used passive fire protection material. So what is fireproof paint? What is the feature of this fireproof measure? What type of paint is being used commonly? The following article will help you answer these questions.

Fireproofing paint for steel structure: Definition, benefits, and applications

Before learning about the fields where fireproofing paint can be applied, let’s find out what fireproofing paint for steel structures is, as well as the benefits that this paint brings to buildings.

1. The definition and classification of fireproofing paint for steel structures

Fireproofing paint 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.

Fireproofing paint for steel structures includes two types:

• Oil-based: This is a popular paint because it works well for indoor and outdoor use. Oil-based paints can adapt to many weather environments, limit harmful agents, and have high water resistance.
• Water-based: This is a safe, environmentally friendly paint that is easy to clean after use. However, water-based fireproof paint can absorb moisture, making it easy to have a thin finish.

2. Benefits of using fireproofing paint for steel structures at construction sites

The outstanding feature of fireproofing paint for steel structures is maximum heat resistance up to 1000oC. The paint’s fire resistance can last up to 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.

3. The range of applications of fireproofing paint 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, 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.

3 popular types of fireproofing paints for steel structures are nowadays

1. Fireproofing paint NTS-101

NTS-101 fireproof paint can help protect factories, warehouses, coastal works, architecture, and other civil works such as hospitals, supermarkets, etc., from fire and harmful effects in the process of exposure to high heat.

Characteristics of fireproof paint for steel structure NTS-101 are as follows:

• The paint surface dries quickly; it only takes 2-3 hours in a temperature environment of 25 degrees Celsius.
• This paint is safe, benign for users, and environmentally friendly because it does not contain toxic volatile components such as lead, mercury…
• After being exposed to fire, the paint does not create much dust and ash, which is safe for firefighting. It can be painted in both indoor and outdoor buildings.

2. Jotun Fireproofing Paint

Jotun is a brand specializing in producing fireproofing paints for steel structures. This coating has been independently approved for the protection of cellulose-insulated structural steel. Jotun paints can be applied up to 500 microns per coat or sprayed up to 1000 microns per coat, helping to create protective coatings of varying thicknesses.

Some outstanding features of Jotun paint:

• Promotes good fire resistance on many surfaces with a time of up to 180 minutes.
• It can be used as an intermediate or topcoat.
• In addition to fire resistance, paint can also resist rust well.

3. Chartek fireproofing paint

Chartek has more than 30 years of experience providing passive fire protection solutions for oil and gas projects. Chartek 1709 fireproof paint is ideal for protecting steel structures from the effects of fire. In addition, this paint is also resistant to long-term corrosion because of its deficient water absorption.

This type of fireproofing paint for steel structures stands out with the following characteristics:

• Chartek 1709 paint is resistant to long-term corrosion because of its deficient water absorption.
• Easy to apply, safe, paint is very quick to dry.
• Optimum cost compared to other paints.
