More about Single-component Silicone Structural Glazing Sealant

Silicone sealants include both one-part and two-part products. This Common Product covers one-component silicone structural glazing sealants. Silicones do not absorb ultraviolet (UV) radiation, so they do not degrade like other materials when subjected to sunlight. Thus, they are used in exterior applications requiring high resistance to UV radiation. Silicone glazing sealants are also resistant to ozone, and extreme temperatures and humidity. In addition, these sealants have high tensile and tear strength. For this reason, they are commonly used in curtainwall applications including both 2- and 4-sided structural glazing. These sealants are composed of reactive siloxanes and silanes that cure upon contact with moisture in the air. Structural sealants can be classified as acid-cure (acetoxy) or neutral-cure (alkoxy). Both types release condensation products upon curing, but acid cure silicone sealants release acetic acid, which can be corrosive to some substrates. This CP covers neutral-cure sealants, which release less corrosive chemicals, such as methanol, upon curing.
