The difference between Silicone Structural Sealant and non-structural adhesive
Silicone structural sealant, also known as "silicone structural sealant". In the glass curtain wall, it is used for the structural silicone adhesive material between the plate and the metal frame, the plate and the plate, and the plate and the glass rib. It is the main stress material of hidden frame and semi-hidden frame curtain wall, and it is also an important factor affecting the safety of glass curtain wall. It has the properties of UV resistance, ozone resistance, good weathering resistance and strong adhesion. Before use, the compatibility test of glass, metal frame, spacer, gasket, positioning block and other sealants should be carried out, and the compatibility test can be used only after passing the test.

The difference between structural adhesive and non-structural adhesive
Structural adhesive refers to high strength (compressive strength> 65MPa, steel-steel positive tensile bonding strength> 30MPa, shear strength> 18MPa), can withstand large loads, and is resistant to aging, fatigue, corrosion, and performance within the expected life. Stable, suitable for strong structural bonding.
Non-structural adhesives have low strength and poor durability, and can only be used for ordinary and temporary bonding, sealing, and fixing, and cannot be used for structural bonding.
The service life of construction projects is generally more than 50 years, and the components bear relatively large and complex stress, which is directly related to the safety of personnel and property. Structural adhesives are widely used in engineering, mainly used for reinforcement, anchoring, bonding, repairing, etc. bonding, etc.
