A Brief about Fire Protective Spray applied Coating based on Mineral

Steel structures lose half of their strength at high temperatures and about 500 °C degrees. Our ancestors used this characterisc to shape their handmade metal designs.

Today, due to the heavy load of high-rise buildings, while construcng such structures, failure to comply with safety standards for fire protecon and prevenon of the heat transfer to the metal structures can lead to disasters such as building collapse in the event of a fire incident.

In accordance with the test standards of passive fire protecon,without thermal protecon coangs, steel structures will reach the crical point within less than 10  minutes from the me of the fire and lose their strength. They are, therefore, highly endangered to fire and necessarily need to be retrofied using fire protecve
coangs. Mineral-based fire protecve coangs are a type of coangs that are generally based on fire-resistant minerals such as vermiculite, dolomite or perlite, as well
as other materials like gypsum and cement, etc. are sprayed onto surfaces such as metals. Due to high thermal resistance and low heat transfer, this type of fire- protecve coang reduces the process of heat transfer in the structure and delays the collapse of the structure for about 2 to 3 hours aer the occurrence of the fire. This, in turn, can provide sufficient me for firefighng and rescue operaons by the fire brigade.


Advantages of Spray applied mineral fire protecon coangs:


  • Reducon of the dead load of the structure
  • due to the low unit weight of the material
  • Avoiding heat transfer from the fire to the surface of the structure
  • Thermal shock resistance
  • No smoke and noxious gases
  • Ease of applicaon
  • Proper adhesion
The above advantages have made the use of mineral-based fire protecve coangs, in parcular, for tackling hydrocarbon and cellulosic fires, to become an unavoidable  choice even compared to other types of fire protecve coangs.
