Built on the 3M Venture Tape 3520CW platform, it combines a dead-soft aluminum foil backing with a cold-weather acrylic pressure-sensitive adhesive. The tape measures 72 mm wide by 45.7 m long per roll and carries a nominal 3.7 mil total thickness. Service temperature range spans -40 degrees F to 250 degrees F, making it suitable for both winter installation conditions and sustained high-heat duct environments. HVAC technicians and sheet metal installers are the primary trades that specify this product.\u003c\/p\u003e\n\u003cp\u003eThis tape is suited for residential and light commercial HVAC ductwork where foil-faced insulation, flexible duct jackets, or sheet metal surfaces require a durable, vapor-retarding seal. Cold-weather acrylic adhesive chemistry allows the tape to bond reliably during low-temperature jobsite conditions without pre-warming the substrate in many applications. It is commonly used during new duct installation, duct repair, and insulation patching tasks where a clean, conformable foil seal is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDead-soft aluminum foil backing conforms to irregular surfaces and duct geometry\u003c\/li\u003e\n  \u003cli\u003eCold-weather acrylic pressure-sensitive adhesive maintains bond at temperatures down to -40 degrees F\u003c\/li\u003e\n  \u003cli\u003eRated for continuous service up to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e3.7 mil nominal thickness provides tear resistance during handling and application\u003c\/li\u003e\n  \u003cli\u003e72 mm width covers standard foil lap seams in a single pass\u003c\/li\u003e\n  \u003cli\u003e45.7 m roll length reduces mid-job roll changes on larger duct runs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on foil-faced insulation, flexible duct outer jackets, and sheet metal duct surfaces in HVAC sealing and patching applications.

De-energize the air handling system and allow ductwork to reach ambient temperature before applying tape to ensure proper adhesive contact. Clean and dry the substrate surface before application — dust, oil, or moisture will reduce adhesion. Apply firm, even pressure across the full tape width using a seam roller or gloved hand to achieve full contact bond.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Dead-soft aluminum foil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Cold-weather acrylic pressure-sensitive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Thickness\u003c\/strong\u003e: 3.7 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 72 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength per Roll\u003c\/strong\u003e: 45.7 m\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Service Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Service Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC duct sealing, foil-faced insulation patching, sheet metal joining\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 322F3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344713711922,"sku":"322F3","price":47.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552568.png?v=1782041305","url":"https:\/\/voomisupply.com\/products\/3m-322f3-aluminum-foil-hvac-tape-3-7-mil-72mm-x-45-7m","provider":"Voomi Supply","version":"1.0","type":"link"}
