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.

  • DOWSIL™ Primer-C
    A solventbased silane adhesion promoter for use in construction applications for painted surfaces.

  • DOWSIL™ 795 Silicone Building Sealant
    A one-part, cold-applied, non-sagging silicone material that cures to a medium modulus silicone rubber upon exposure to atmospheric moisture.

  • DOWSIL™ 790 Silicone Building Sealant
    A one-part silicone formulation that cures in the presence of atmospheric moisture to produce a durable, fire-resistant, flexible and ultra-low-modulus silicone rubber building joint seal.

  • DOWSIL™ 3363 Insulating Glass Sealant
    A high strength secondary two-part silicone sealant specifically designed for high strength applications, where conventional sealants with lower strength would lead to increased joint sizes. It enables economical joint sizes in highly demanding insulating glass applications such as: high wind in tall buildings, hurricane loads, cold-bent glass or high impact loads such as bomb blast. Smaller joint dimensions can be filled faster and therefore lead to productivity enhancements.

  • DOWSIL™ 7091 Adhesive Sealant
    High performance, neutral cure silicone adhesive/sealant.

  • DOWSIL™ 3362 Insulating Glass Base and Catalyst

    A two component room temperature neutral curing silicone sealant specifically developed for the manufacture of high performance insulated glass units. It is suitable for insulating glass units used in residential and commerical, and structural glazing applications.


  • DOWSIL™ 796 Neutral Silicone
    A one-part, low modulus, neutral curing silicone sealant specifically developed for the sealing of PVC-U, glass, glazed surfaces and brick work. It is very popular for perimeter sealing applications of windows and doors.

  • DOWSIL™ 993 HV/GER Structural Glazing Catalyst

  • DOWSIL™ 895 Structural Glazing Sealant
    A one-part, neutral curing silicone sealant designed specifically for the structural bonding of glass, metal and other building components. It can also be used for adhering stiffening elements to building panels.

  • DOWSIL™ 1200 OS Primer, UV Traceable

    Primer for silicone adhesives and sealants.


  • DOWSIL™ 1200 OS Primer
    An air drying primer supplied as a dilute solution of moisture reactive materials in volatile siloxane and is used to improve both the quality and speed of adhesion development to room temperature vulcanizing silicone sealants to a variety of common non-porous substrates.

  • DOWSIL™ 121 Structural Glazing Sealant
    A fast-curing structural silicone sealant for use in structural and weatherseal applications.

  • DOWSIL™ 791 Weatherproofing Sealant
    A one-part, medium-modulus, elastomeric sealant designed for general weathersealing. It is a silicone formulation that cures to a flexible and curable silicone rubber building joint seal.
