High-strength aluminum foil tape with cold weather acrylic adhesive, moisture-stable liner, and thermally conductive backing for demanding industrial applications requiring heat shielding and environmental protection.
3M™ Aluminum Foil Tape 3367 is a premium high-strength foil tape engineered with cold weather acrylic adhesive and a moisture-stable liner designed for demanding industrial applications. This versatile tape excels in extreme temperature and humidity environments, providing superior performance and durability across a wide range of environmental conditions. The malleable aluminum foil backing resists moisture, weather, UV degradation, and many chemicals, making it ideal for both indoor and outdoor applications.
The tape features a thermally conductive backing that helps dissipate heat over a wider surface area, enhancing lighting efficiency and thermal management. The moisture-stable liner prevents wrinkling in high humidity conditions, while the acrylic adhesive delivers exceptional temperature, UV, and solvent resistance for strong, lasting bonds. With a tensile strength of 30 lb/in and 6% elongation at break, this tape provides reliable performance in demanding applications.
3M™ Aluminum Foil Tape 3367 is suitable for masking, sealing, seaming, shielding, harness wrapping, joining, and heat shielding applications. It serves as an excellent barrier against moisture, dust, dirt, and mild chemicals. The tape is ideal for die-cut applications and is widely used in the transportation, specialty vehicle, construction, and appliance industries. As with all 3M products, it comes with exclusive technical expertise and application advice.
