Technical Information
3M 8673 is a 14 mil transparent polyurethane protective tape engineered for abrasion, erosion, and impact protection of aircraft leading edges, painted metal, and composite panel surfaces in aerospace and industrial applications. The thick PU film acts as a sacrificial protective layer that absorbs rain erosion, foreign object impact, and surface abrasion damage, preserving the underlying painted or composite substrate. At 12″ width, it covers broad surface areas on wings, fuselage panels, and nacelles in a single piece application. The transparent film allows visual inspection of the protected surface without tape removal, and the pressure-sensitive adhesive provides a clean, repositionable bond.
Why Choose 3M 8673 Polyurethane Protective Tape?
- 14 Mil Thick PU Protection — Sacrificial erosion and abrasion shield for aircraft surfaces
- 12″ Wide Coverage — Broad format for wing leading edges and large panel protection
- Transparent Film — Visual surface inspection without tape removal
- Repositionable Adhesive — Clean, repositionable application on painted aircraft surfaces
- 36 Yard Roll — Generous length for large aircraft surface protection programs
Frequently Asked Questions
Q: What is 3M 8673 Polyurethane Tape 12″ x 36 Yard used for?
A: 3M 8673 in 12″ x 36 Yard is used for protecting aircraft leading edges, wide fuselage panels, and composite structures from rain erosion, abrasion, and foreign object impact damage in aerospace maintenance and manufacturing.
Q: What is the MPN for 3M 8673 12″ x 36 Yard?
A: The Manufacturer Part Number (MPN) is 70-0000-8321-12.
Q: How thick is 3M 8673 Polyurethane Tape?
A: 3M 8673 is 14 mils (0.014″) thick, providing substantial sacrificial protection while remaining flexible and conformable to curved aircraft surface profiles.
Q: Is 3M 8673 approved for commercial aircraft use?
A: 3M 8673 polyurethane protective tape is used in aerospace applications. Consult the applicable aircraft maintenance manual and relevant aviation authority for specific approval requirements for the aircraft type and surface location.
Q: How does 3M 8673 compare to paint for leading edge protection?
A: 3M 8673 polyurethane tape provides physical abrasion and erosion protection superior to paint alone on leading edges. It can be replaced during scheduled maintenance without repainting, reducing aircraft downtime and maintenance costs associated with leading edge erosion damage.
