3M 431 Aluminum Foil Tape
This 3M 431 aluminum foil tape serves automotive, aviation, construction, electronics and general maintenance tasks. The continuous roll suits indoor and outdoor environments. Professionals and DIY users rely on it for sealing, shielding and repair jobs that demand a durable metal-backed tape.
Pressure-sensitive adhesive for daily handling
The pressure-sensitive adhesive bonds to metal ducts, panels and equipment without extra tools or heat. A 2-inch width covers seams and joints in a single pass, reducing overlap time on the job site. The silver foil conforms to irregular surfaces and resists moisture, so the bond holds through vibration and weather exposure.
Temperature range -65 to 300 degrees F
The tape performs from -65 degrees F up to 300 degrees F without losing adhesion or backing integrity. This range covers cold-storage facilities, engine compartments and high-heat ductwork in one product. The aluminum foil reflects radiant heat and resists flame spread, keeping the assembly stable through thermal cycling.

Questions about this item
What temperature range does the 3M 431 aluminum foil tape withstand?
The 3M 431 aluminum foil tape performs from -65 degrees to 300 degrees F, making it suitable for extreme indoor and outdoor environments across automotive, aviation, and construction applications.
What surface preparation does the 2-inch wide 3M 431 tape require for proper adhesion?
Clean the mounting surface thoroughly to remove dust, oil, and moisture before applying the 2-inch wide tape; skipping this step causes the most adhesion failures on metal ductwork and equipment.
How do you apply the 3M 431 foil tape from its continuous roll without wrinkles?
Unroll the 5-yard continuous roll steadily while pressing firmly with a squeegee or roller; the common mistake is stretching the tape during application, which creates wrinkles and reduces sealing performance.
