  • DOWSIL™ 995 Silicone Structural Sealant
    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%.

  • 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™ 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.


  • DOWSIL™ 7091 Adhesive Sealant
    High performance, neutral cure silicone adhesive/sealant.

  • DOWSIL™ 890-SL Silicone Joint Sealant
    A one-part, cold-applied, easy-to-use, self-leveling silicon material that cures to an ultra-low-modulus silicone rubber upon exposure to atmospheric moisture. The cured silicone rubber remains flexible over the entire temperature range expected in pavement applications.

  • DOWSIL™ 1200 OS Primer
    An air drying primer supplied as a dilute solution of moisture reactive materials in volatile siloxane and is used to improve both the quality and speed of adhesion development to room temperature vulcanizing silicone sealants to a variety of common non-porous substrates.

  • DOWSIL™ 556 Cosmetic Grade Fluid
    A polyphenylmethylsiloxane for use in skincare, suncare, color cosmetic, hair care, and antiperspirant / deodorant applications. INCI Name: Phenyl Trimethicone

  • DOWSIL™ Primer-C OS

  • DOWSIL™ 121 Structural Glazing Sealant
    A fast-curing structural silicone sealant for use in structural and weatherseal applications.

  • 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.
