Coil cement is a sealing material used to fill the gap between coils and electronic devices, usually consisting of synthetic rubber and filler. It has certain fire resistance and can resist the combustion of the flame at a certain temperature. However, its fire resistance depends on the specific formulation and use environment.

Generally speaking, the fire resistance of coil mortar is relatively low and cannot completely replace refractory materials. In situations requiring high safety and fire prevention, professional refractory materials should be used. Therefore, if you need to use refractories, you should choose professional refractories that meet safety standards, rather than just relying on coil mortar.

It is important to note that no material can be considered in terms of fire safety... It's safe. Therefore, when using any material, you should pay attention to fire safety and take necessary safety measures, such as installing fire extinguishers and establishing fire isolation belts.
