It seals and bonds joints in applications where wide temperature swings and chemical resistance are critical. The sealant operates across a range of -76 degrees F to 356 degrees F, making it suitable for HVAC housings, mechanical enclosures, and food-processing equipment. It reaches a tack-free state in 20 minutes and achieves full cure in 24 hours. HVAC technicians, plumbers, and maintenance professionals use this sealant where a flexible, durable silicone seal is required around metal, glass, or plastic substrates.\u003c\/p\u003e\n\u003cp\u003eThe 2112531 is suited for both residential and commercial service work. Common applications include sealing around ductwork flanges, equipment access panels, plumbing penetrations, and food-safe equipment joints. Its food-safe rating under 21 CFR 177.2600 makes it appropriate for installations in commercial kitchens and food-processing facilities. The black color blends with dark surfaces and is useful when aesthetics matter in visible joint locations. The compact 3 oz tube is a single-use or spot-repair size well matched to service calls and maintenance kits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRTV silicone chemistry provides flexible, permanent sealing after cure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -76 degrees F to 356 degrees F suits high-heat and cold environments\u003c\/li\u003e\n  \u003cli\u003eTack-free in 20 minutes, fully cured in 24 hours\u003c\/li\u003e\n  \u003cli\u003eFood-safe rating per 21 CFR 177.2600 for use in food-contact adjacent installations\u003c\/li\u003e\n  \u003cli\u003eMeets MIL-A-46106 military specification\u003c\/li\u003e\n  \u003cli\u003eAdheres to glass, metal, and plastic substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to adhere to glass, metal, and plastic surfaces.

HVAC technicians and maintenance professionals typically apply this product with a standard caulk-tip tube — cut the tip to the desired bead size before dispensing. Allow the full 24-hour cure time before exposing the joint to liquids or mechanical stress. Work in adequately ventilated spaces, as RTV silicone releases acetic acid during cure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChemical Type\u003c\/strong\u003e: RTV Silicone\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 732\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 3 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -76 degrees F (-60 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 356 degrees F (180 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTack-Free Dry Time\u003c\/strong\u003e: 20 minutes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Cure Time\u003c\/strong\u003e: 24 hours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdheres To\u003c\/strong\u003e: Glass, Metal, Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFood Safe\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: 21 CFR 177.2600, MIL-A-46106\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DOW CORNING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2112531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DOW CORNING","offers":[{"title":"Default Title","offer_id":51542122725682,"sku":"2112531","price":21.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc12f7d3d74f2669186adc5362af7f1c.jpg?v=1785892739","url":"https:\/\/voomisupply.com\/products\/dow-corning-2112531-rtv-silicone-joint-sealant-3-oz-black","provider":"Voomi Supply","version":"1.0","type":"link"}
