Industrial Adhesives & Tapes


Choosing the Right Tape for Paint Stripping and More

 Substrates and Adhesion – Know Your Surface

When masking windows, seams, wheels and more on an aircraft for paint stripping, there’s one important thing to keep in mind—only 3M™ Aluminum Foil Tapes 425 and 427 are approved by the Department of the Navy Technical Order TO 1-1-8 for this tough task.

This list of products is so short because the job is just that demanding. Tapes need to provide strong initial adhesion, stand up to paint stripper for up to 72 hours, and then still remove cleanly. A tape’s failure during the paint stripping process could lead to costly damage and additional downtime, so it’s critical to get this product selection right. Aluminum Foil Tapes 425 and 427 can also be certified to meet SAE-AMS-T-23397, another key validation of their performance—and one that most other tapes just can’t achieve.

Great Solution for Metal Finishing

Beyond masking, these workhorse tapes have several other important applications in the aerospace industry. Since they meet the requirements of FAR 25.853(a) and 25.855, they can serve as tapes to seal off areas and prevent the introduction of foreign object debris. The tapes are also often used for metal finishing applications. The same resistance to chemicals that makes the tapes so useful for paint stripping also helps them mask against the harsh chemicals used in electroplating and anodizing.

With qualifications like these, the only choice to make is which of the two tapes will best suit your needs.

  • Aluminum Foil Tape 425 is self-wound for easy application. It resists temperatures up to 300oF (149oC).
  • Aluminum Foil Tape 427 is a linered version of Aluminum Foil Tape 425 . It can be die cut into shapes—to match windows, for instance—helping increase productivity and precision.

Whichever you choose, Aluminum Foil Tapes 425 and 427 have earned the certifications to assure you of their outstanding performance.
