Many people confuse high-temperature-resistant coatings with fire-resistant coatings, thinking that they can withstand high temperatures, so fire protection should also be possible, but in fact there is an essential difference between the two. The high temperature outside and the baking on the flame are not the same. The "function" of the two is common.  

The high temperature resistant coating has the characteristics of high temperature resistance and heat resistance. The fire retardant coating is a kind of flame retardant coating with fire prevention function. High temperature resistant coatings are widely used in heating equipment, electrothermal processing, electrical equipment, electronic products, boilers, flues, kilns, hoods and other products. However, there are many combustible substrates, such as wood, power plants, industries, and mines, which cannot be processed by simply using high-temperature coatings. So, how should we distinguish between the two?

1. Understand the difference in effectiveness

High temperature resistant paint is a kind of high temperature anticorrosive and antirust paint. Fireproof paint is a kind of paint that delays and reduces damage to items in the event of a fire.

2. Understand the difference in the case of an open flame

Some high-temperature resistant coatings can be used in open fires, and fire-resistant coatings contact with open flames will slow down the spread of fire and delay heat transfer.

3. Understand the difference in functionality

High temperature resistant coatings have multiple functions such as high corrosion resistance, high temperature resistance and oxidation resistance, and their service life is relatively long. Fire-retardant coatings are non-flammable or non-flammable, and have the functions of flame retardant and fire-proof.

4. Understand the difference in operating temperature

High temperature resistant coatings are generally around 200°C-1200°C, while fire retardant coatings are used at normal room temperature.

5. Understand the difference in scope of application

High temperature resistant coatings are mainly used for industrial or domestic heating components, while fire retardant coatings are used for more wood structures or steel structure materials, and some are used for cables.

After a basic comparison, I believe everyone is very puzzled, why are fire-resistant coatings so popular in modern steel structure buildings? First of all, let us see what its advantages are!

1. The fire-retardant coating itself is fire-resistant or non-flammable, so that the protected substrate does not directly contact the air, delaying the ignition of the object and reducing the burning speed.

2. It also has low thermal conductivity, which can delay the transfer of fire temperature to the bottom of the protected layer.

3. The fireproof coating uses heat to decompose incombustible gas, dilute the heat of the protected object to decompose, and isolate the combustible gas.

4. Nitrogen-containing flame retardant coatings decompose nitrogen dioxide, hydrogen nitride and other groups by thermal decomposition, and react with organic free chains and terminal chains to lower the temperature.

5. The intumescent flame retardant coating expands by heating to form a foam insulation layer, which seals the protected object, delays the transfer of heat to the substrate, and prevents the object from burning or reducing the burning intensity due to temperature rise.

Fire retardant coatings play an active and important role in actual production and application. Our company focuses on the research and development of high temperature resistant functional ceramic coatings. With many years of research history, we strive to make it more professional and effective in various functional fields, and realize difficult work. The thorough problem solving of the situation allows you to truly feel the high-efficiency application of high-temperature coatings in various fields.
