Glass curtain walls usually use silicone structural adhesive. Silicone structural adhesive has the characteristics of high strength, good tensile and shear resistance, high resistance to repeated stretching and compression, 

and good elastic modulus, which can effectively prevent glass from breaking due to deformation. It can directly connect glass to the surface of metal components to form a single assembly component, meet the design

 requirements of curtain walls with fully hidden or semi-hidden frames, and is also suitable for structural bonding and sealing of insulating glass.

In addition, silicone weather-resistant sealant is also commonly used in glass curtain walls. It is mainly used to fill the gaps generated when curtain wall glass and other materials are pasted. It has good resistance to wind and rain,

 can avoid thermal expansion and contraction caused by climate change, and can still be firmly bonded after the joint width changes.

In practical applications, the following points should also be noted:

- Select appropriate structural adhesives according to relevant specifications and design requirements, and ensure that their quality meets the standards.

- Before construction, the shelf life and appearance of the structural adhesive should be checked to ensure that there are no abnormalities.

- Strictly follow the instructions for use of the structural adhesive for construction, including the control of environmental conditions such as construction temperature and humidity.

- Before using glue on the secondary frame of the curtain wall, check whether there is any problem with the specifications of the double-sided adhesive strip. Note that before bonding the glue, the hand should not touch the 

position where the aluminum material is bonded with glue. The error between the glue and the frame should be controlled within 1mm, and the joints should be kept straight and neat.

- After the frame is bonded with glue, check whether its quality is qualified, and classify and stack the frame models and lengths. When the glass is bonded to the frame, wipe it with cotton cloth to avoid secondary pollution and affect the overall effect.

At the same time, the performance and quality of structural adhesives are crucial to the safety and durability of glass curtain walls. Therefore, it is recommended to choose products produced by regular manufacturers and have 

professionals perform construction and maintenance. If you have specific questions about the selection and use of glass curtain wall structural adhesives, you can also consult relevant building experts or curtain wall construction units.
