Prefabricated buildings, or prefabs, are buildings with components (wall, roof, and floor) that are manufactured in a factory or manufacturing plant.
These components can be fully or partially assembled in a factory, then transferred to the site. This method of building construction is preferred due
to its cost efficiency, fast turnaround, and reutilization. Common applications of prefabricated buildings are temporary construction facilities,
office spaces, medical camps, evacuation centers, schools, apartment blocks, and single-detached houses.

Sealant is an indispensable topic when talking about prefabricated buildings. It plays a vital role in connecting prefabricated structures. Whether it is the exterior protection of the building or the interior decoration, whether it is a window structure or other forms of decorative structure, each assembly structure is a separate unit, so the splicing of each unit will create a gap. These seams directly affect the waterproof performance of the prefabricated building. The building sealant is mainly used to fill the gap left by the assembly structure and is required to have functions such as waterproof, anti-corrosion, sound insulation, fire prevention, decoration, structural elastic connection, safety, and durability. According to different environmental factors, there will be other functions such as radiation protection and oxidation prevention.

MS sealants are undoubtedly the most proper one to meet the requirements of prefabricated buildings. Firstly, MS sealants are compatible with most materials. Concrete is a loose porous material, which contains a lot of alkaline substances. MS adhesives have excellent adhesion to most substrates such as concrete and stone. Secondly, under the action of load and temperature, there will be relative displacement between the exterior wall panels, and the sealant must have certain elastic capacity and recovery capacity. MS sealants with just low modulus have strong displacement resistance. Thirdly, MS sealants are UV resistant and durable, which can prevent the prefabricated exterior wall panel from aging due to wind, rain, and ultraviolet radiation. Lastly, Ms sealants do not contain any water-soluble components, and the plasticizer can not exude, there is no pollution.
