Professional-grade aluminum foil repair tape with pressure-sensitive rubber adhesive, flame and moisture resistant, ideal for metal surface repairs, HVAC sealing, and insulation applications. UL 723 rated, operates -10°F to 180°F.
Scotch® Aluminum Foil Tape 3311 is a professional-grade 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 preservation of adhesive properties.
This versatile tape delivers outstanding resistance to flame, moisture, weather, UV degradation, water vapor, odor and smoke transmission, making it ideal for demanding industrial applications. The tape is thermally conductive and heat reflective, making it particularly effective for sealing aluminum-faced insulation seams and joints. With a total thickness of 3.6 mil and width of 2.83 inches, each roll provides 50 yards of continuous coverage. The tape performs exceptionally well in temperatures ranging from -10°F (-12.2°C) to 180°F (82.2°C) and is UL 723 rated for fire safety compliance.
Designed for industrial and occupational use, this 6-roll case provides comprehensive coverage for maintenance professionals, contractors, and industrial facilities. The conformable backing acts as a vapor barrier, ensuring the integrity of insulation systems at critical seams and joints. Whether for HVAC applications, appliance repair, automotive work, or general construction maintenance, Scotch® Foil Tape 3311 delivers reliable, long-lasting adhesion and protection in most weather conditions.
