    3M™ Aluminum Foil Tape 425 is a dead-soft aluminum foil backed tape with a special transparent synthetic acrylic adhesive, making this the best general purpose foil product available. This tape is ideal for masking, sealing, seaming, shielding, chemical stripping, harness wrapping, joining, electroplating, plastic protection, chemical milling, heat shielding, heat reflecting, and paint stripping.

    3M™ Aluminum Foil Tape 425 serves has excellent heat and light reflection to protect against high temperature and U.V. degradation. It's also an effective barrier against moisture, dust, flame, dirt and mild chemicals used in paint stripping and masking. The thermally conductive backing helps maximize efficiency by dissipating heat over a wider surface area. The synthetic acrylic adhesive provides superior temperature, U.V. and solvent resistance to produce a strong, lasting and reliable bond. It provides excellent age life and is ideal for harsh, long-term indoor and outdoor environments. Recommended Applications Aircraft paint stripping maskant Moisture barrier in “white goods” appliances General purpose heat reflector and heat dissipater Mechanically hold wires and cooling coils in “white goods” appliances Repair tears on truck trailers and aircraft Splicing of thin gauge foils General purpose holding, patching, sealing applications – indoors and out Designed to seal the cut edges of 3M™ Interam Mats and 3M™ Duct Wrap to complete total encapsulation Aluminum is just one of the metal-backed tapes available from 3M. Our line of foil tapes resist failure from many common sources of degradation, including moisture, ultraviolet rays and many chemicals. As with all 3M products, our Aluminum Foil Tape 425 comes with exclusive 3M technical expertise and application advice. 3M™ Aluminum Foil Tape 425 meets U.L. 746C (File E 122798) and 723, Class "L" for low flammability rating (File R 7311). It can be certified to meet SAE-AMS-T-23397 and L-T-80C and meets F.A.R 25.853(a), O447. Temperature use range is from -65° to 300°F (-54° to 149°C.)
