Fire-resistant sealants belong to building materials that combine several qualities. Such material can be used to fill seams or various cracks, repair chipped brickwork in a fireplace, or when carrying out other types of work on surfaces that are used at high temperatures or come into contact with open fires. Thus, fire sealant is used for internal refractory works..
The main areas of application for refractory sealants based on silicone or acrylic are in sealing the various gaps that form between floors and walls. Also, such material is used to process joints between the wall and window frames..
But the main purpose of refractory sealants is to use them as a filler for panel cavities with refractory status. Also, such material is very widely used for laying heating routes, erection of structures made of concrete, steel, brick..
The main advantage of fire-fighting sealants is excellent adhesion to various surfaces, including porous ones. It is also necessary to take into account that acrylic refractory sealants are elastic, which allows it to be used when sealing deformed joints. Such sealants can be applied on both dry and damp surfaces, so you can work with such material in all weather conditions..
All fireproofing sealants have a certain resistance class. As for the types of refractory sealants, they are distinguished based on the basis on which they are made. Silicone or liquid glass can be used as a basis..
The choice of sealant for use should be based on the characteristics of the surface to be treated and the general nature of the work. Usually, all types of refractory sealants have the same properties, but, nevertheless, each of them has its own characteristics, since they have different curing times and withstand temperature thresholds, gas tightness levels and shrinkage values..
The choice of refractory sealants for use should be done with special responsibility, since sometimes the fire safety of the building, its individual rooms, and sometimes the life of the people in them depends on it..
