Structural Glazing

DowSil® 983 Structural Glazing Sealant is a two-part, neutral-cure, RTV silicone sealant and is designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum1, although DowSil® Primer C is recommended for fast and consistent adhesion, especially to Kynar and other high-performance substrates approved for architectural structural glazing applications.

DowSil® 795 Silicone Building Sealant is a one-part, cold-applied, non-sagging silicone material that cures to a medium modulus silicone rubber upon exposure to atmospheric moisture. It can be used for both Structural and nonstructural glazing and can provide Structural attachment of many panel systems .

DowSil® 995 Silicone Structural Sealant is a one-component, self-priming, shelf-stable, neutral-cure, elastomeric adhesive specifically formulated for silicone structural glazing and exhibits excellent unprimed adhesion to most building substrates. This product has superior unprimed adhesion for structural glazing applications for hurricane or impact rated windows and doors. It has a movement capability of +/- 50%.
