At 20 mil thick and 0.5 inches wide on a 72-yard roll, it delivers a conformable bond to high surface energy substrates including metals, glass, and many plastics. The acrylic adhesive construction provides cushioning, vibration damping, and impact resistance alongside strong holding power. Weighing 1.3 pounds per roll, it is suited for assembly, mounting, and bonding applications in manufacturing, glazing, signage, and building panel work. It carries a UL 746C listing, confirming suitability for use with polymeric materials.\u003c\/p\u003e\n\u003cp\u003eThis tape is used in applications requiring a clean, invisible bond line with no visible fasteners. Typical scenarios include attaching architectural panels, mounting trim, bonding nameplates, and securing display components. The 72-yard roll length supports production-line use and reduces roll changeover frequency. Trades and assembly technicians working on commercial glazing, sign fabrication, electronics assembly, and general industrial bonding are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 mil thickness for conformability and gap-filling on slightly uneven surfaces\u003c\/li\u003e\n  \u003cli\u003eClear acrylic adhesive on both sides with PE film liner for clean handling\u003c\/li\u003e\n  \u003cli\u003eBonds high surface energy substrates including metal, glass, and select plastics\u003c\/li\u003e\n  \u003cli\u003eProvides cushioning, vibration damping, and impact resistance in bonded assemblies\u003c\/li\u003e\n  \u003cli\u003eUL 746C listed for use with polymeric materials\u003c\/li\u003e\n  \u003cli\u003e72-yard roll length reduces changeover in production or high-volume installation work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for bonding high surface energy substrates such as metals, glass, and many rigid plastics. Best performance is achieved on clean, dry, properly prepared surfaces.

Apply firm, even pressure across the tape after placement to ensure full adhesive contact. Allow dwell time at room temperature before placing the assembly under full service load. Follow applicable building codes and substrate manufacturer guidelines when using adhesive tape in structural or load-bearing panel applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTape Series\u003c\/strong\u003e: VHB Tape 4905\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Clear\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 20 mil\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 72 yards\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdhesive Type\u003c\/strong\u003e: Double-sided pressure-sensitive acrylic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner\u003c\/strong\u003e: PE film\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.3 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Roll\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: UL 746C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 21200243912\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: 21200-24391\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346453496114,"sku":"21200-24391","price":2982.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310515709.jpg?v=1782080788","url":"https:\/\/voomisupply.com\/products\/3m-21200-24391-vhb-tape-4905-clear-0-5in-x-72yd-20-mil","provider":"Voomi Supply","version":"1.0","type":"link"}
