Dow Corning 99179246 Rtv Silicone Joint Sealant 10.1 Oz

Product Description

The DOW CORNING 99179246 is a white RTV silicone joint sealant packaged in a 10.1 oz cartridge, part of the 732 Series. It forms a flexible, durable seal on glass, metal, and plastic surfaces and is rated for continuous service from -76 degrees F to 356 degrees F. The sealant reaches a tack-free state in 20 minutes and achieves full cure in 24 hours. It meets 21 CFR 177.2600 food-safe standards and MIL-A-46106 military spec, making it a capable choice for demanding mechanical, HVAC, plumbing, and food-service equipment sealing applications. Trade professionals and maintenance technicians use it for gasketing, sealing penetrations, and securing fittings where silicone flexibility and temperature resistance are required.

This sealant is suited for both residential and commercial applications where a reliable, high-temperature-resistant joint seal is needed. Typical uses include sealing ductwork penetrations, HVAC equipment housings, plumbing access points, and equipment enclosures in food-processing or commercial kitchen environments. Its adhesion to glass, metal, and plastic makes it versatile across multiple trade disciplines. The 10.1 oz cartridge is designed for use with a standard caulk gun, allowing controlled application in tight or elevated work areas.

Installation Notes

Apply to clean, dry surfaces free of oil, dust, and loose material for best adhesion. This product is typically applied by HVAC technicians, plumbers, or maintenance mechanics using a standard caulk gun. Allow adequate cure time before exposing the joint to fluids or mechanical stress. Work in a well-ventilated area, as uncured silicone releases acetic acid vapor during cure.
