  • 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™ Primer-C OS

  • 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™ 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.

  • XIAMETER™ PMX-200 Silicone Fluid 350 cSt
    100% active, 350 cSt, polydimethylsiloxane polymer. INCI Name: Dimethicone

  • 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™ Q1-9226 Thermally Conductive Adhesive
    Typical applications include bonding organic and ceramic substrates to heat sinks for electronic control modules in automotive applications. It is a two-part, gray, 1:1 mix ratio, heat cure, moderate flow, self-priming, thermally conductive adhesive.

  • SYL-OFF™ 4000 Catalyst
    General purpose catalyst which is compatible with all Syl-off® brand solvent based and solventless release coating systems as well as Plantinum cure silicone PSAs.

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

  • 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%.
