Silicon has a wide range of uses in the construction industry, mainly in the following aspects:

1. Sealing materials
Application examples: silicone sealant, silicone rubber sealing strips, etc.
Features: These sealing materials have excellent weather resistance, high temperature resistance, chemical corrosion resistance and aging resistance.
Use: Used for door and window sealing, curtain wall sealing, etc. of buildings to ensure the airtightness and durability of building structures.

2. Waterproof materials
Application examples: waterproof coatings, waterproof glue, etc.
Features: Silicone waterproof materials have excellent water resistance, weather resistance and aging resistance.
Use: Used for waterproofing of roofs, basements, bathrooms, etc. of buildings to effectively prevent water penetration and leakage.

3. Adhesive materials
Application examples: silicone structural adhesive, silicone rubber adhesive, etc.
Features: These adhesive materials have excellent bonding strength, weather resistance and chemical corrosion resistance.
Use: Used for bonding and fixing of glass curtain walls, metal plates, stones, etc. of buildings to ensure the stability and safety of building structures.

4. Silicone coatings
Features: Silicone coatings have good weather resistance, UV resistance, and certain fire resistance.
Use: Used for exterior wall coating of buildings to protect the exterior walls of buildings from climate and environmental erosion.

5. Thermal insulation materials
Application examples: thermal insulation coatings, thermal insulation adhesives, etc.
Features: Organic silicon thermal insulation materials have excellent thermal insulation and weather resistance.
Use: Used for thermal insulation of buildings, reducing energy consumption of buildings, and improving indoor comfort.

6. New thermal insulation materials
Example: SiO2 aerogel (nanoporous super thermal insulation material).
Features: High porosity, low density, low thermal conductivity, and excellent thermal insulation performance.
Application: Used for aerogel energy-saving windows, aerogel coatings, aerogel new panels, etc., to improve the energy-saving effect of buildings.

7. Structural reinforcement and protection
Application: Organic silicon resin adhesives, organic silicon primers, etc.
Function: It can not only enhance the strength of the building structure, but also provide waterproof, water-resistant, mildew-proof, antibacterial and other protections to extend the service life of the building.

8. Improved safety
Application: Structural sealants used in protective or impact-resistant windows.
Function: Provide more protection for residents or pedestrians in severe weather, fire, earthquake, etc., and reduce the risk of broken glass fragments falling off the window frame.

In summary, silicone plays an important role in the construction industry, and its diverse product forms and excellent performance characteristics provide strong support for the development of the construction industry.
