Quickly learn about building curtain wall silicone structural sealant！

Sophisticated, elaborate, and innovative—to describe today's high-rises would be spot-on. A common feature of many of these new buildings is their sleek exterior appearance--curtain wall, which is often the result of structural silicone sealant. Curtain wall silicone sealants are bonding materials between the structure of the plate and metal frame, plate and plate, and plate and glass ribs. 

Curtain wall silicone sealant is the main stress material of the hidden frame and semi-hidden frame curtain wall, and also a major factor affecting the safety of glass curtain walls. Curtain wall silicone sealant is specially designed for weatherproofing and sealing application under severe conditions. The weatherproof sealant is particularly suited for curtain walls and metal cladding facades.

Severe outdoor environment conditions require high-performance silicone sealants tested to meet the demanding performance requirements of contemporary curtain wall technology. Curtain wall construction sealants must withstand a unique combination of environmental pressures. Sealant joints must have high UV resistance to exposure and environmental pollutants such as acid rain; function effectively under daily thermal movements and wind loads; and weather resistance, good bonding strength, ozone resistance, and other properties. TNS-721 is a typical curtain wall silicone sealant with excellent performance like strong adhesion, high strength, high elasticity, high modulus, and strong ability to resist movement.

Importantly, before use, The first thing is to do the compatibility test of glass, metal frame, spacer, gasket, positioning block, and another sealant.
