Coated with a pressure-sensitive cold-weather solvent acrylic adhesive, it delivers quick tack at normal temperatures and maintains reliable adhesion in low-temperature job site conditions. The FSK laminate backing combines aluminum foil, reinforcing scrim, and kraft paper to produce a tape with high puncture resistance and tear resistance. At 6 inches wide and 50 yards long, each roll covers substantial run length on a single duct section. HVAC installers and insulation mechanics reach for this tape when sealing ductboard seams and fibrous blanket joints that require a vapor-retarding, durable face bond.\u003c\/p\u003e\n\u003cp\u003eThe 7100043912 is suited to residential and light commercial HVAC duct systems where FSK-faced rigid ductboard or flexible duct insulation is used. It conforms to curved, corrugated, and irregular duct surfaces without bridging or lifting, making it practical for field sealing where surface geometry varies. The flexible backing makes installation straightforward without specialized applicators or primers on standard FSK substrates. It performs in cold job site environments, including unconditioned attics, crawl spaces, and mechanical rooms during winter installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFSK laminate backing — aluminum foil face, reinforcing scrim, and kraft paper layer — for use on fibrous ductboard and sheet metal ducts\u003c\/li\u003e\n  \u003cli\u003eCold-weather acrylic adhesive maintains tack and bond strength in low-temperature conditions\u003c\/li\u003e\n  \u003cli\u003eHigh puncture and tear resistance for long-term durability in demanding install environments\u003c\/li\u003e\n  \u003cli\u003eFlexible construction conforms to curved, irregular, and fibrous duct surfaces\u003c\/li\u003e\n  \u003cli\u003e6-inch width and 50-yard length reduce seam count and roll changes on long duct runs\u003c\/li\u003e\n  \u003cli\u003eNo special tools or application methods required for field installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with FSK-faced insulation board and duct assemblies.

Before applying, ensure the FSK substrate surface is clean, dry, and free of dust or oil to achieve full adhesive contact. Press tape firmly across the full width of the seam to eliminate air pockets. Follow local mechanical codes and the duct manufacturer's application guidelines for seam treatment on pressurized duct systems.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTape Width\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTape Length\u003c\/strong\u003e: 50 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Foil\/Scrim\/Kraft (FSK) laminate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Pressure-sensitive cold-weather solvent acrylic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 28.002 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 12.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 12.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 12.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051128955876\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: 7100043912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342835450162,"sku":"7100043912","price":537.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530849.jpg?v=1782008119","url":"https:\/\/voomisupply.com\/products\/3m-7100043912-fsk-foil-tape-6-inch-x-50-yd-silver","provider":"Voomi Supply","version":"1.0","type":"link"}
