Polyurethane Protective Tapes

Substructure corrosion in aircraft areas exposed to recurring moisture, such as lavatories, galleys and doorways, is a major industry challenge. 3M Aerospace is responding to this need by making the protection of these “wet areas” easier with the introduction of improved 3MPolyurethane Protective Tapes that cover the seams in floor panel joints and wide-area tapes to protect larger areas exposed to moisture.

These flame-retardant tapes provide a durable moisture barrier with a long service life. 3M wet area protection tapes are constructed of a tough, puncture-resistant thermoplastic elastomer coated with a pressure-sensitive adhesive. The tapes provide a durable and flame-resistant barrier that prevents costly corrosion damage to aircraft floor systems, and can be installed easily and quickly for a variety of applications, including seam sealing, wide wet area protection and beam protection. High elongation gives the tapes excellent conformability, providing effective coverage of contoured areas, and their dual liner construction results in better productivity and fewer wrinkles or bubbles during application. Furthermore, the transparency of the seam sealing tape allows for easy visual inspection of floor panel sealants.

The tapes also meet the FAA’s expected new policy statement for 14CFR 25.853 that will provide standardized testing and establish acceptable methods of compliance for flame resistance.
