DOWSIL™ 1200 OS Primer, UV Traceable

Primer for silicone adhesives and sealants.

Properties

These values are typical properties and are not intended for use in preparing specifications.

  • Color Yes No Colorless
  • Flash Point, Closed Cup Yes No 1 °C
  • Specific gravity at 23°C (73.4°F) Yes No 0.82
  • Viscosity Yes No 1 mPa.s
  • 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™ 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™ 121 Structural Glazing Sealant
    A fast-curing structural silicone sealant for use in structural and weatherseal applications.

  • DOWSIL™ 756 SMS Building Sealant
    A medium-modulus elastomeric sealant designed for weatherproofing sensitive porous stone and metal panel substrates to reduce residue rundown and substrate staining in new and remedial construction.

  • DOWSIL™ 3363 Insulating Glass Sealant
    A high strength secondary two-part silicone sealant specifically designed for high strength applications, where conventional sealants with lower strength would lead to increased joint sizes. It enables economical joint sizes in highly demanding insulating glass applications such as: high wind in tall buildings, hurricane loads, cold-bent glass or high impact loads such as bomb blast. Smaller joint dimensions can be filled faster and therefore lead to productivity enhancements.

  • 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™ 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™ 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%.
