How high temperature can fire retardant coatings withstand

How many degrees of high temperature can the fire retardant coating withstand

Shenzhen Situjia Technology Co., Ltd. has been focusing on the research and development of water-based inorganic ceramic coatings and the main productionFire-retardant and flame-retardant coating Fire-retardant coating is a passive fire-resistant material painted on the surface of the protected object (such as steel structure). . Water-based and solvent-based products are divided according to the medium. Fire retardant coatings generally do not talk about how many degrees of high temperature they can withstand. The industry term is: fire resistance limit, unit: hour.

In other words, the protected object has a limit value that can withstand the test of fire. No matter what structure the building is exposed to for a long time, it will collapse. Fire retardant coatings play a role in isolating the surface of the protected object, delaying the collapse of the building, and gaining valuable time for rescue and fire fighting.

Speaking of the fire resistance limit, it is also the time limit for the fire retardant coating to lose the protection of the protected object.

For example, for a steel beam of a steel structure building, the fire resistance limit of the fire-resistant paint is 2 hours, and the thickness of the fire-resistant paint is 2mm. That is to say, when the fire retardant coating is brushed on the steel beams of this building, when the thickness of the paint film reaches 2mm, the steel beams of this building can withstand 2 hours in case of fire.

Of course, these data are all done in the lab under ideal conditions Yes, the country has type inspection standards for related products, and you can also refer to the national standard GB14907-2002.
