It forms a flexible, durable seal suited for applications that demand broad thermal tolerance, rated from -60 degrees C to 180 degrees C. The cured silicone resists moisture, vibration, and temperature cycling, making it a reliable choice for sealing, bonding, and gasketing tasks in mechanical and HVAC work. Licensed tradespeople and maintenance technicians reach for this product when a long-lasting, heat-resistant seal is needed on equipment housings, ductwork joints, and mechanical assemblies.\u003c\/p\u003e\n\u003cp\u003eThis sealant is appropriate for both residential and commercial service environments. It performs well in applications where thermal expansion and contraction stress a joint — such as around furnace panels, heat exchanger flanges, rooftop unit penetrations, and general mechanical equipment enclosures. The 300 mL tube format works with a standard caulking gun, making it practical for field service and shop use alike. HVAC technicians, plumbers, and general mechanical contractors commonly stock this product for a range of sealing and repair tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRTV silicone chemistry cures at room temperature to a flexible, permanent seal\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -60 degrees C to 180 degrees C\u003c\/li\u003e\n  \u003cli\u003eWhite color allows clean, finished appearance on visible joints\u003c\/li\u003e\n  \u003cli\u003e300 mL tube size works with standard caulking guns\u003c\/li\u003e\n  \u003cli\u003eSeries 738 formulation suited for moisture-resistant and vibration-resistant sealing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose RTV silicone sealant suitable for use on metal, glass, and most non-porous substrates encountered in HVAC, plumbing, and mechanical service applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eClean and dry all surfaces thoroughly before applying sealant to ensure proper adhesion and cure. Allow adequate cure time before exposing the joint to thermal cycling or mechanical stress. When working near energized equipment, follow lockout-tagout procedures before application. Consult the manufacturer safety data sheet for ventilation requirements, as silicone sealants release acetic acid or other byproducts during cure depending on formulation.\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: 738\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContainer Size\u003c\/strong\u003e: 300 mL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -60 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 180 degrees C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 99180508\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DOW CORNING","offers":[{"title":"Default Title","offer_id":51542104342834,"sku":"99180508","price":1401.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117dbb4c13cb19cde6e7cf7cc204d09f.jpg?v=1785892170","url":"https:\/\/voomisupply.com\/products\/dow-corning-99180508-rtv-silicone-sealant-300-ml-white","provider":"Voomi Supply","version":"1.0","type":"link"}
