Safe and Sustainable for the Structural Silicone Sealant in Ultra High-Rise Building Curtains

Abstract

The properties of the structural silicone sealant under standard condition and after aging conditions were characterized. The results showed that the structural silicone sealant had very good ability to resist the ultraviolet in the long time. In the other aging environment conditions, the different failure time for the structural silicone sealant were appeared. The value of the maximum strength under the different mechanical aging factors obviously existed in the structural silicone sealant with different compositions. The residual strength that the attenuation ratio is more than 75% standard strength would keep the ultra high-rise building curtains safe and sustainable.
