Enhanced Performance in High Heat and Humidity: Designed to withstand high heat and humidity, the 3M™ Aluminum Foil Tape 427 features a thermally conductive aluminum backing that effectively dissipates heat, reducing hot spots and protecting sensitive materials from extreme temperatures. This tape is perfect for applications requiring a durable, heat-resistant, and reliable solution, such as die-cutting processes where precision and performance are crucial.
Durability Against Harsh Conditions

The unique formulation of the 3M™ Aluminum Foil Tape 427 makes it resistant to chemicals, moisture, weathering, and UV exposure, ensuring long-term reliability and performance even in the most challenging environments. The tape’s highly engineered acrylic adhesive provides strong adhesion yet removes cleanly after use, making it ideal for harsh masking applications. Its ability to withstand exposure to flames and maintain low flammability adds an extra layer of safety in critical applications.
