DOWSIL 795

Data Sheet

Overview

Overview

DOWSIL 795 Silicone Building Sealant is a one-part, neutral-cure, architectural-grade sealant that easily extrudes in any weather and cures quickly at room temperature. This cold-applied, non-sagging silicone material cures to a medium modulus silicone rubber upon
exposure to atmospheric moisture. The cured sealant is durable and flexible enough to accommodate ± 50 percent movement of original joint dimension when installed in a properly designed weather seal joint. In a properly designed structurally glazed joint, the sealant is strong enough to support glass and other panel materials under high wind load.

Features:

  • Suitable for most new construction and remedial sealing applications
  • Versatile – high performance structural glazing and weather sealing from a single product
  • Available in 15 standard colors; custom colors also available
  • Excellent weatherability virtually unaffected by sunlight, rain, snow, ozone and temperature extremes of -40°F (-40°C) to 300°F (149°C)
  • Excellent unprimed adhesion to a wide variety of construction materials and building components, including anodized, alodined, most coated and many Kynar® painted aluminums
  • Ease of application – ready to use as supplied
  • Ease of use – all temperature gunnability, easy tooling and low-odor cure byproduct
  • Meets global standards (Americas, Asia and Europe)
