The tape measures 3 inches wide by 100 feet long and carries a 17 mil total thickness, making it robust enough for demanding sheet metal applications. Construction consists of a conformable aluminum foil backing, an aggressive butyl mastic adhesive, and a blue LDPE film liner that strips cleanly before application. The low-VOC adhesive bonds quickly to sheet metal surfaces and resists moisture and solvents after cure. HVAC technicians and sheet metal mechanics are the primary installers for this product.\u003c\/p\u003e\u003cp\u003eThis tape is used on residential and commercial sheet metal ductwork where a code-compliant, long-term air seal is required. Typical applications include sealing longitudinal and transverse duct joints, patching sheet metal duct damage, and sealing connections on round, square, or irregularly shaped fittings. The butyl mastic adhesive stays workable for several minutes after initial contact, allowing repositioning in tight mechanical spaces before the permanent bond sets. It is listed under UL 723 and UL 181B-FX, and meets applicable LEED contribution criteria for both energy performance and low-emitting materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAggressive butyl mastic adhesive forms a permanent, water-tight and air-tight seal on sheet metal duct\u003c\/li\u003e\n\u003cli\u003e17 mil thickness with conformable aluminum foil backing handles irregular and round duct geometry\u003c\/li\u003e\n\u003cli\u003eRepositionable for several minutes after application for accurate placement in confined spaces\u003c\/li\u003e\n\u003cli\u003eLow-VOC content — can contribute toward LEED EQ Credit 4.1 (Low Emitting Materials)\u003c\/li\u003e\n\u003cli\u003eResistant to moisture and solvents after cure\u003c\/li\u003e\n\u003cli\u003eMeets UL 181B-FX requirements for use on Class 1 flex and sheet metal duct systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use on sheet metal duct systems and listed to UL 181B-FX for flexible air duct and air connector applications.

Power down and de-energize the air handling system before beginning duct sealing work. Peel the blue LDPE film liner completely before applying the tape, and press firmly along the full length of the tape to ensure full adhesive contact. Do not apply over surfaces contaminated with oil, dust, or loose oxidation — clean and dry the substrate before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Foil Sealant Tape, 1-Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 17 mil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Aluminum foil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive\u003c\/strong\u003e: Butyl rubber mastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiner\u003c\/strong\u003e: Blue LDPE film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rating\u003c\/strong\u003e: -20 to 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplicable Standards\u003c\/strong\u003e: UL 723, UL 181B-FX, PSTC-101, LEED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVOC Content\u003c\/strong\u003e: Low VOC\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NASHUA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 367-17_3X100FT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NASHUA","offers":[{"title":"Default Title","offer_id":51284042744114,"sku":"367-17_3X100FT","price":59.48,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277692.jpg?v=1781067003","url":"https:\/\/voomisupply.com\/products\/nashua-367-17_3x100ft-foil-sealant-tape-3in-x-100ft-17-mil","provider":"Voomi Supply","version":"1.0","type":"link"}
