  • 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™ Contractors Weatherproofing Sealant
    A one-part, moisture cure, medium modulus sealant that provides durable, flexible, watertight joints and offers outstanding unprimed adhesion to most non-porous substrates. It is specifically developed for sealing dynamically moving joints.

  • DOWSIL™ 983 Structural Glazing Sealant Base and Curing Agent

    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 OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.
