DOWSIL™ 983 (KR) Structural Glazing Sealant Base and Catalyst

A two-part silicone formulation. As supplied, the base is a smooth, white paste and the curing agent is a black paste. Once catalyzed, the material cures to a high-modulus, flexible silicone rubber that is suitable for use in structural and weatherseal applications. It features excellent adhesion to most common construction materials, a physical property profile that is more than sufficient for structural adhesive and weatherseal applications, a non-corrosive by-product, and excellent weatherability, durability and recovery after repeated extension and compression up to 25%. It is compatible with reflective glass, laminated glass and most insulating glass. It can be used in deep narrow joints to obtain a full and complete cure.(Product manufactured in S.Korea)

  • DOWSIL™ 795 Structural Glazing Sealant

    A one-component, neutral-curing silicone sealant intended for structural bonding of glass, metal and other materials. It is a medium-modulus structural sealant with excellent adhesion to a wide range of materials. The product has been tested and passed ASTM C1184 Structural Sealant Specification and it has ±50% movement capability in accordance with the ASTM C719 test. 

  • 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™ 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™ 982 FS Silicone Insulating Glass Sealant
    A two-part silicone formulation. As supplied, the base is a smooth, white paste. The curing agent is available in black or gray and is a pourable liquid. Once catalyzed, the material cures to a high modulus, silicone rubber that is intended for IG applications, including IG units for heat mirror applications and IG units which will be structurally glazed.

  • DOWSIL™ 982 Silicone Insulating Glass Sealant Base and Catalyst

    A two-part silicone sealant designed for use as a secondary sealant in a dual-sealed insulating glass unit, as well as in an insulating glass unit that will be structurally glazed. The product cures to a durable, high-modulus, flexible silicone seal that is chemically stable and creates a weathertight bond. It has excellent unprimed adhesion to glass and metal substrates, such as galvanized steel and aluminum.

  • 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.
