50+ Years of Commercial Facade Success

Imagine the Possibilities

Redefining the possibilities of the modern skyline

As buildings get taller and architectural designs get more sophisticated, architects need products and design systems they can rely on.

For more than five decades, Dow has been a pioneer working alongside architects as they implemented their most ambitious designs, utilizing sealant and bonding solutions for weatherproofing and silicone structural glazing to keep their buildings stronger for longer.


Which silicones?

DOWSIL™ 121 Silicone Structural Glazing Sealant – An easy-to-use and fast-curing sealant, for use in structural and weather-sealing applications, which can be applied on-site or in-shop. This sealant simplifies facade installation and reduces repair time.

DOWSIL™ Transparent Structural Silicone Adhesive (TSSA) for fixed-point exterior glass facades – An innovative, high strength, structural adhesive, TSSA provides a bonding option for crystal clear, point fixed glass external facades that negates the need to drill and bolt through glass – eliminating the potential for leakage of gas and thermal bridging.

DOWSIL™ DefendAir 200 – This barrier prevents water infiltration with the ability to “breathe.” The water-based coating dries to form a flexible membrane that is impervious to liquid water, but allows moisture vapor to escape.

Proven performance

Two separate studies confirm what industry experts have believed for years, and hard data verifies what field performance has long indicated: DOWSIL™ SSG sealants deliver long-term performance and durability.

Through scientific testing:

  • ETAG 002 testing indicates 25-year-old DOWSIL™ structural glazing sealant is theoretically proven for another 25 years
  • BAM durability testing of a Dow Consumer Solutions structural glazing sealant predicts a 50-year service life
