DESCRIPTION

COLORS

Dow Corning® 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 t dimension when installed in a properly designed weather seal t. In a properly designed structurally glazed t, the sealant is strong enough to glass and other materials under high wind load.

Dow Corning 795 Silicone Building Sealant is available in 16 colors: white, limestone, champagne, natural stone, gray, black, bronze, sandstone, adobe tan, dusty rose, rustic brick, blue spruce, anodized aluminum, and charcoal. Custom colors may be ordered to match virtually any substrate.

APPROVALS/ SPECIFICATIONS Dow Corning 795 Silicone Building Sealant meets the requirements of:  Federal Specification TT-S 001 543A (COM-NBS) Class A for silicone building sealants  Federal Specification TT-S00230C (COM-NBS) Class A for one- component building sealants  ASTM Specification C 920 Type S, Grade NS, Class 50, Use NT, G, A and O  ASTM Specification C 1184 for structural silicone sealants  Canadian Specification CAN219.13- M82

HANDLING PRECAUTIONS

HOW TO USE Please consult the Dow Corning Americas Technical Manual, Form No. 62-1112, for detailed information on state-of-the- art application methods and t design. Please your local Dow Corning Sales Application Engineer for specific advice. Preparation Clean all ts, removing all foreign matter and contaminants such as grease, oil, dust, water, frost, surface dirt, old sealants or glazing compounds and protective coatings.

PRODUCT SAFETY INFORMATION REQUIRED FOR SAFE USE IS NOT INCLUDED IN THIS DOCUMENT. BEFORE HANDLING, READ PRODUCT AND SAFETY DATA SHEETS AND CONTAINER LABELS FOR SAFE USE, PHYSICAL AND HEALTH HAZARD INFORMATION. THE SAFETY DATA SHEET IS AVAILABLE ON THE DOW CORNING WEBSITE AT DOWCORNING.COM, OR FROM YOUR DOW CORNING SALES APPLICATION ENGINEER, OR DISTRIBUTOR, OR BY CALLING DOW CORNING CUSTOMER SERVICE.

USABLE LIFE AND STORAGE

Application Method Install backing material or t filler, setting blocks, spacer shims and tapes. Mask areas adjacent to ts to ensure neat sealant lines. Primer is generally not required on non-porous surfaces, but may be necessary for optimal sealing of certain porous surfaces. A test placement is always recommended. Apply Dow Corning 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 t surfaces. Remove masking tape as soon as the bead is tooled.

When stored at or below 27°C (80°F), Dow Corning 795 Silicone Building Sealant has a shelf life of 12 months from the date of manufacture. Refer to product packaging for “Use By Date.”

PACKAGING INFORMATION Dow Corning 795 Silicone Building Sealant is supplied in 10.3-fl oz (305mL) disposable plastic cartridges that fit ordinary caulking guns, 20-fl oz (590- mL) sausages and 2- and 4.5-gal (7.5- and 1 7-L) bulk containers.

LIMITATIONS Dow Corning 795 Silicone Building Sealant should not be used:  In structural applications without prior review and approval by your local Dow Corning Sales Application Engineer  In below-grade applications  When surface temperatures exceed 50°C (122°F) during installation  On surfaces that are continuously immersed in water  On building materials that bleed oils, plasticizers or solvents that may affect adhesion
