Dow Corning 99179259 Rtv Silicone Joint Sealant 10.1 Oz

Product Description

The DOW CORNING 99179259 is an RTV silicone joint sealant supplied in a 10.1 oz cartridge. It is formulated for sealing and bonding applications across a wide operating temperature range of -76 degrees F to 356 degrees F (-60 degrees C to 180 degrees C). Gray in color, this Series 732 sealant bonds to glass, metal, and plastic substrates. It reaches a tack-free state in 20 minutes and achieves full cure in 24 hours. HVAC technicians, plumbers, and general maintenance contractors use this product to seal joints, penetrations, and fittings where silicone flexibility and temperature resistance are required.

This sealant is suited for both residential and commercial applications where a durable, flexible seal is needed on metal ductwork, plumbing penetrations, glass, and plastic components. Its food-safe designation under 21 CFR 177.2600 makes it appropriate for use in food-processing environments and commercial kitchen equipment installations. The cartridge format is compatible with standard caulk guns for controlled application in the field.
