  • DOWSIL™ 123 Silicone Seal-All Colors

    A pre-formed, ultra-low modulus silicone extrusion that is bonded to substrates using DOWSIL™ 791 Silicone Perimeter Sealant or DOWSIL™ 795 Silicone Building Sealant. This product can be used in both new and remedial construction 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.

  • 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.
