Product Description:
The 3M™ 8641/NP-36173 Aircraft Belly Protective Tape is an industrial-grade, non-perforated polyurethane tape engineered to protect aircraft fuselage, chines, landing gear doors, cargo sills, and other lower surfaces from Foreign Object Damage (FOD), abrasion, erosion, scratches, and minor impacts. With a robust acrylic foam adhesive, it conforms to complex curves while providing long-lasting durability under extreme environmental conditions. The medium dark gray color (FS 36173) is standard across military and commercial aviation, making it suitable for a wide range of airframes, including Lockheed C-130, Boeing, Airbus, and other commercial or military fleets. The 24″ width and 36-yard length provide ample coverage for large areas, reducing the number of seams and installation time.
The 3M™ Aircraft Belly Protective Tape 8641 is the ultimate solution for safeguarding aircraft underbellies. Engineered with a 16-mil polyurethane coating and a 25-mil thick pressure-sensitive acrylic foam adhesive, it offers unmatched durability and adhesive strength. Its perforated design ensures easy application. Compliant with safety regulations, it's perfect for aviation maintenance, providing uncompromised protection and longevity for your aircraft fleet.
