Silicone Sealant Wacker SG

Specification of Silicone Sealant Wacker SG

Glass facades, especially in Asia, are increasingly installed and tied to construction sites. At ZAK Glass Technology, WACKER has presented a new silicone sealant specifically for on-site installation. WACKER SG 79 Structural Glazing is a one-component silicone sealant that heals quickly after reacting with atmospheric humidity. "Healed completely, sealants can be stretched up to 500 percent. "This allows the product to compensate for movement in the connection by up to 50 percent of the width of the gap," the company claims.

WACKER SG 79 opposes temperatures between –30 C and +80 C and is therefore suitable for structural coating applications in various climate zones. This product cures almost odorless and can be processed at temperatures ranging from 5 to 40 C. WACKER SG 79 is suitable for all conventional building materials such as glass, steel, concrete or stone, even without primer.
