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.
DEFENDAIR™ 200C Air and Weather Barrier Coating – 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.
