Modern building exterior wall enclosure generally uses curtain walls made of different materials such as glass, stone, and aluminum plates, which are more beautiful, energy-saving, and easy to maintain. When installing curtain walls, silicone structural adhesive is used to fix the glass on the keel and seal the joints to ensure aesthetics and safety. Due to the special nature of installation, it is required that the silicone structural adhesive used must have high requirements such as high modulus and high performance to ensure the safety and durability of the curtain wall. must be airtight, waterproof, energy-efficient and, when needed in specific environments, soundproof and protect against dust or insects. Doors and windows can be made of different materials such as aluminum alloy, wood or a combination of materials. Usually, aluminum doors and windows are the most common, and silicone sealants are increasingly applied in bonding the gaps between the aluminum alloy and glass and other materials.
