At 3.4 mil total thickness, the tape combines a Tedlar PVF film backing with an acrylic adhesive system. The PVF backing provides durability against weathering and chemical exposure, while the acrylic adhesive delivers strong, lasting bonds to a variety of substrates. It is sized 1 inch wide by 72 yards per roll and is suited for use by building envelope contractors, glaziers, and experienced maintenance professionals.\u003c\/p\u003e\u003cp\u003eThis tape is used primarily for sealing seams on outdoor building panels, window and door perimeters, and similar exterior assemblies subject to severe weather exposure. It is also used as a hinge seal on shower doors where moisture resistance is required over time. Applications span both commercial and residential construction and renovation work, wherever a flexible, UV-stable film tape is needed to maintain a weathertight seal at joints and transitions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTedlar PVF film backing for weathering and UV resistance in severe outdoor exposure conditions\u003c\/li\u003e\n\u003cli\u003eAcrylic adhesive system provides durable, long-term bond to building panel substrates\u003c\/li\u003e\n\u003cli\u003e3.4 mil total tape thickness balances conformability with mechanical protection\u003c\/li\u003e\n\u003cli\u003e1 inch width suitable for sealing panel seams, window perimeters, and door frames\u003c\/li\u003e\n\u003cli\u003e72-yard roll length reduces splice frequency on longer runs\u003c\/li\u003e\n\u003cli\u003eMoisture-resistant construction makes it appropriate for wet-area applications such as shower door hinge seals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on outdoor building panel seams, window and door perimeter joints, and hinge seals on shower doors where severe exposure and moisture resistance are required.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface preparation is critical before application — substrates should be clean, dry, and free of dust, oil, and loose material. Apply firm, even pressure across the full width of the tape using a roller or squeegee to ensure full adhesive contact. In cold-weather installations, allow the tape and substrate to reach a workable temperature before application, as acrylic adhesives require adequate temperature for proper bond development. Work area should comply with applicable building codes for exterior envelope sealing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTape Thickness\u003c\/strong\u003e: 3.4 mil (0.09 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Tedlar PVF film\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Acrylic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 72 yards per roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.53 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Roll\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00021200056840\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 7100028874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347927499058,"sku":"7100028874","price":6921.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310514448.jpg?v=1782116272","url":"https:\/\/voomisupply.com\/products\/3m-7100028874-weather-resistant-film-tape-838-white","provider":"Voomi Supply","version":"1.0","type":"link"}
