DOWSIL™ 993 Structural Glazing Base and Catalyst

A two-component, neutral curing silicone formulation specifically developed for the structural bonding of glass, metal and other building components.
Burj Khalifa Building in Dubai, United Arab Emirates

Structural silicone glazing is today’s most innovative form of curtainwall construction. Glass, ceramic, metal, stone and composite panels are adhered to building frames using structural silicone adhesive/sealants. These adhesives not only support the panels; they also transmit windloads to the structure and seal the building from the elements and allows total vision glass without thermal bridges.

DOWSIL™ 993 Silicone Structural Glazing Sealant meets European standard for structural glazing (ETA-01/0005) in all color shades. Fast and easy catalyst color change in production will be supported by DOWSIL™ 3535 Catalyst Cleaner.

DOWSIL™ 993 Silicone Structural Glazing Sealant was used at Burj Khalifa, with a height of 828 m the world’s tallest building and also the highest installation of an aluminium and glass facade.
