Designed with a tough acrylic adhesive, it forms a strong and lasting bond on metal, plastic and composite surfaces. The adhesive offers excellent resistance to heat, UV light, moisture, and solvents. This makes the 3M Foil Tape 431 perfect for both indoor and outdoor use, even in harsh environments.

The tape is thermally conductive and heat reflective, allowing it to manage temperature efficiently. It also acts as a reliable heat resistant tape, ideal for sealing, patching, splicing and masking jobs. Use it to hold cooling coils, repair truck trailers, or seal joints in HVAC systems. It performs consistently and resists degradation over time.

Thanks to its low moisture vapour transmission rate, the 3M 431 provides a tight, secure seal against air, moisture and dust. It is non-degradable and flame resistant, which adds to its long-term durability. The tape’s clean, metallic surface also reflects heat and light, helping to improve energy efficiency in heating and cooling systems.

This aluminium tape is often used as a maskant in electroplating aluminium because it will not contaminate the plating bath. It meets F.A.R 25.853(a) and UL 723 Class L standards, proving it performs well in demanding professional environments.
