Silicone chemistry provides flexible, durable bonds and seals that resist degradation at sustained elevated temperatures up to 200 degrees C. Licensed HVAC technicians, electricians, and mechanical contractors reach for this type of sealant when sealing penetrations, encapsulating components, or bonding dissimilar materials where thermal cycling would crack or degrade standard adhesives. The gray color blends with metal housings and electrical enclosures common in commercial and residential mechanical systems.\u003c\/p\u003e\u003cp\u003eThis sealant is suited for sealing around ductwork penetrations, electrical junction box entries, HVAC cabinet seams, and similar applications where a flexible, heat-resistant seal is required. It performs in both residential and light commercial mechanical systems. The tube format delivers controlled application without requiring a caulk gun, making it practical for targeted repairs and fieldwork where access is tight or quantities are small.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSilicone chemical base provides flexibility and resistance to thermal cycling\u003c\/li\u003e\n\u003cli\u003eRated for continuous service up to 200 degrees C\u003c\/li\u003e\n\u003cli\u003eGray color suits metal panels, enclosures, and mechanical housings\u003c\/li\u003e\n\u003cli\u003eTube container allows direct application without additional dispensing tools\u003c\/li\u003e\n\u003cli\u003eAppropriate for sealing, bonding, and encapsulating in high-heat environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement silicone sealant for use in residential and commercial HVAC, electrical, and mechanical service applications requiring high-temperature performance.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical — clean and dry all substrate surfaces before applying sealant to ensure proper adhesion. Power down electrical systems and isolate HVAC equipment before applying sealant near live components or energized panels. Allow full cure time before returning the sealed assembly to service. Application and use in occupied spaces should comply with local ventilation requirements and applicable building codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical Type\u003c\/strong\u003e: Silicone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Sealant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContainer Type\u003c\/strong\u003e: Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 200 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 3145 90ML GRY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DOW CORNING","offers":[{"title":"Default Title","offer_id":51542059221298,"sku":"3145 90ML GRY","price":2774.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7d0341d3050ff778406ea461b7b557bc.jpg?v=1785890819","url":"https:\/\/voomisupply.com\/products\/dow-corning-3145-90ml-gry-silicone-sealant-gray-tube","provider":"Voomi Supply","version":"1.0","type":"link"}
