Industrial Foil Tape 425

3M 70008500996 is an aluminum foil tape supplied in a 60-yard roll for sealing, shielding and repair tasks. The transparent finish allows visual inspection of the substrate after application. It suits maintenance engineers, HVAC installers and packaging operations that require a conformable metal-backed adhesive.

Sustained Load Behaviour

The acrylic adhesive maintains bond strength across repeated thermal cycles without rapid degradation. The foil backing resists moisture ingress and chemical exposure during long-term service. The construction delivers consistent performance where vibration or temperature fluctuation would weaken standard tapes.

Build Quality and Connectors

The 425-series construction provides a dead-soft aluminum carrier that conforms to irregular surfaces without spring-back. The liner releases cleanly to speed up application on ductwork, seams or cable shielding. The roll format supports both hand dispensing and automated equipment in daily use.

Questions about this item

Will the adhesive on the 3M 70008500996 foil tape degrade from heat if I run my HVAC system continuously?

The 3M 425 aluminum foil tape is designed for thermal cycling on ducts and plenums; its acrylic adhesive maintains bond through repeated heating and cooling cycles in normal HVAC operation.

What surface preparation or primer do I need before applying this 1/2" wide foil tape?

Clean the metal or flex duct with a lint-free cloth and isopropyl alcohol; the pressure-sensitive acrylic adhesive on the 3M 425 tape bonds to clean, dry surfaces without a separate primer.

Can I use this transparent 3M foil tape to patch tears in the older silver foil-faced insulation wrap I already have installed?

Yes; the 1/2-inch width conforms to curved seams and the transparent carrier lets you align the repair over the existing silver jacket while the acrylic adhesive bonds to the aged foil surface.
