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. 

Features & Benefits:

• Highly resistant to weather, UV and temperature extremes
• One-part, medium-modulus neutral-cure adhesive/sealant silicone material
• Supports glass and other panel materials under high wind load
• Weatherproofs substrates such as glass, aluminum, steel, painted metal, EIFS, granite & other stone, concrete, brick, plastic
• Ready to use as supplied with all-temperature gunnability, easy tooling and low-odor curing
• 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 by product
• Meets global standards (Americas, Asia and Europe)

How to Use:

• Preparation:
  • Clean all joints, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants or glazing compounds and protective coatings.
• Application Method:
  • Install backing material or joint filler, setting blocks, spacer shims and tapes. Mask areas adjacent to joints to ensure neat sealant lines. Primer is generally not required on nonporous surfaces, but may be necessary for optimal sealing of certain porous surfaces. A test placement is always recommended.
  • Apply DOWSIL 795 Silicone Building Sealant in a continuous operation using positive pressure. (The sealant can be applied using many types of air-operated guns and most types of bulk dispensing equipment.) Before a skin forms (typically within 15 minutes), tool the sealant with light pressure to spread the sealant against the backing material and joint surfaces. Remove masking tape as soon as the bead is tooled.

Shelf Life And Storage: When stored at or below 27°C (80°F), DOWSIL 795 Silicone Building Sealant has a shelf life of 12 months from the date of manufacture. Refer to product packaging for Use By Date.
