In the field of construction, silicone has become a key raw material for sealants due to its excellent performance. Building sealants are used to fill gaps such as expansion joints and settlement joints in buildings, and must have good weather resistance, adhesion and elasticity.

The weather resistance of silicone sealants is unparalleled. The silicon-oxygen bonds in its molecular structure are extremely stable and can resist erosion by natural factors such as ultraviolet rays, ozone, wind and rain. Under long-term exposure to ultraviolet rays, ordinary sealants are prone to aging and cracking, while silicone sealants can maintain stable performance. For example, in the expansion joints of the exterior walls of high-rise buildings, silicone sealants can withstand long-term exposure to the sun and rain, effectively preventing rainwater leakage and air infiltration, and maintaining the thermal insulation performance of the building.
Adhesion is another major advantage of silicone sealants. It can bond well with a variety of building materials, such as glass, metal, concrete, etc. In the installation of glass curtain walls, silicone structural sealants firmly bond the glass to the metal frame, which not only ensures the overall beauty of the curtain wall, but also ensures that the glass does not fall off under the action of external forces such as strong winds and earthquakes, ensuring the safety of the building.

The high elasticity of silicone sealants is also crucial. Buildings will have certain displacements due to temperature changes and foundation settlement. Silicone sealants can expand and contract with the deformation of the building and always remain sealed. At the expansion joints of bridges, sealants need to withstand the huge displacement caused by the thermal expansion and contraction of the bridge. With high elasticity, silicone sealants can be repeatedly stretched and compressed without failure, ensuring the stability of the bridge structure and driving safety.

In addition, silicone sealants also have good chemical corrosion resistance, can resist acid rain, oil pollution and other erosion, and extend the service life. It is widely used in special environment buildings such as chemical buildings and sewage treatment plants. Its good water resistance can be used in humid areas such as bathrooms and kitchens to effectively prevent problems such as structural damage and mold caused by water penetration.

In short, silicone gives building sealants excellent performance, which is indispensable in modern buildings and is of great significance to improving building quality, extending service life and ensuring safety performance.
