Guide You To Intuitively Understand The Characteristics of Silicone Structural Sealant in Curtain Wall Engineering

Glass building curtain walls organically integrate the functional and decorative functions of wind protection, rain protection, lighting, insulation, insulation, cold resistance, noise resistance, and air infiltration prevention of the building's peripheral structure.

It is a complex of architectural technology, functionality, and art, widely applied worldwide.

The development of glass building curtain walls cannot be separated from the development of silicone structural sealants! Today, the editor will take you to have a visual understanding of the characteristics of silicone structural sealant in curtain wall engineering.

01

Tensile resistance and high strength

Silicone structural sealant must have high tensile and shear strength, as well as resistance to repeated tensile, compressive, and peel bonding strength.

It should also have high elasticity and be able to maintain the basic shape of its adhesive layer even under high positive and negative stresses, to prevent glass from cracking due to excessive deformation.

02

Weather resistance and durability

Silicone structural sealant must not only resist the invasion of wind and rain, but also adapt to the thermal expansion and contraction between curtain wall glass panels caused by climate temperature differences, so that the joint width can still be firmly bonded.

03

Irreplaceability

Silicone structural sealant is generally used for hollow glass in framed aluminum alloy glass curtain walls. The function of silicone structural adhesive for insulating glass cannot be replaced by polysulfide adhesive. Otherwise, under negative wind pressure, there is a risk of the outer glass falling. Therefore, ordinary adhesive cannot be used to replace silicone structural sealant.

Silicone structural sealant is widely used for structural bonding and sealing of glass curtain walls due to its high and low temperature resistance, weather aging resistance, ozone resistance, good adhesion to various substrates, and strong displacement resistance. Therefore, the performance of silicone structural sealant plays a significant role in the safety of curtain walls.

Today, the editor brings you a silicone structural sealant: CSJ-905 (certified structural adhesive) silicone structural sealant for curtain wall engineering.

Scope of application: 1. Adhesive sealing for large-scale curtain wall structural engineering; 2. Adhesive sealing of glass and aluminum materials; 3. Suitable for industrial and construction engineering use; 4. Multiple materials for joint filling and structural sealing.
