Technical Information
3M 8673 is a 14 mil transparent polyurethane (PU) protective tape designed for abrasion, erosion, and impact protection of aircraft leading edges, painted metal surfaces, and composite panels in aerospace and industrial applications. The thick polyurethane film provides a sacrificial protective layer that absorbs abrasion, rain erosion, and foreign object impact damage, protecting the underlying painted or composite surface from premature wear. The transparent film allows visual inspection of the protected surface without tape removal, and the pressure-sensitive adhesive provides a clean, repositionable bond to aircraft surfaces.
Why Choose 3M 8673 Polyurethane Protective Tape?
- 14 Mil Thick PU Film — Sacrificial abrasion and erosion protection for aircraft surfaces
- Transparent Film — Inspect protected surfaces visually without removing the tape
- Aircraft Leading Edge Rated — Protects against rain erosion and foreign object impact damage
- Repositionable Adhesive — Clean, repositionable application on painted aircraft surfaces
- 12″ x 36 Yard Roll — Wide format for large aircraft surface and panel protection projects
Frequently Asked Questions
Q: What is 3M 8673 Polyurethane Protective Tape used for?
A: 3M 8673 is used for protecting aircraft leading edges, painted metal surfaces, and composite panels from abrasion, rain erosion, and foreign object impact damage in aerospace maintenance and manufacturing applications.
Q: What is the MPN for 3M 8673 12″ x 36 Yard?
A: The Manufacturer Part Number (MPN) is 70-0000-8531-12.
Q: How thick is 3M 8673 Polyurethane Tape?
A: 3M 8673 is 14 mils (0.014″) thick, providing substantial sacrificial protection against surface abrasion and impact while remaining flexible and conformable to curved aircraft surface profiles.
Q: Is 3M 8673 approved for use on commercial aircraft?
A: 3M 8673 polyurethane protective tape is used in aerospace applications. Consult the applicable aircraft maintenance manual and your aviation authority for specific approval requirements for the aircraft type and surface location.
Q: How long does 3M 8673 protective tape last on aircraft surfaces?
A: Service life depends on aircraft operating environment, surface location, and inspection/replacement intervals specified in the maintenance program. Leading edges in erosive environments may require more frequent inspection and replacement than less-exposed surfaces.
