Premium aluminum foil repair tape with pressure-sensitive rubber adhesive, flame and moisture resistant, ideal for metal surface sealing and insulation applications in industrial settings.
Scotch® Aluminum Foil Tape 3311 is a premium general-purpose repair and maintenance tape specifically engineered for temporary and emergency repair of metal surfaces. Featuring a high-tack, pressure-sensitive rubber adhesive combined with a conformable aluminum foil backing, this dead-soft tape provides exceptional adhesion to both smooth and irregular surfaces, including low-energy substrates. The sturdy aluminum foil backing is mounted on a paper liner for ease of deployment and adhesive preservation.
This versatile 2.0-inch tape offers superior resistance to flame, moisture, weather, UV degradation, water vapor, odor, and smoke transmission, making it ideal for demanding industrial applications. With excellent thermal conductivity and heat-reflective properties, it's perfect for sealing aluminum-faced insulation seams and joints while improving system efficiency. The tape performs exceptionally well in a wide temperature range from -10°F (-12.2°C) to 180°F (82.2°C) and is UL 723 rated for compliance with safety standards.
Each case contains 24 rolls of 10-yard length tape with 3.6-mil total thickness, providing reliable, long-lasting results you can trust from 3M. The tape bonds on contact and acts as an effective vapor barrier to ensure insulation system integrity at critical seams and joints. Ideal for aerospace, appliance, automotive, construction, electronics, and general industrial applications.
