Premium aerospace-grade 18 mil polyurethane protective tape with high shear acrylic adhesive, offering superior resistance to scratches, tears, erosion and punctures for helicopter rotor blade protection and aircraft maintenance applications.
The 3M™ Polyurethane Protective Tape 8681HS is an 18 mil leading edge erosion protection tape specifically engineered for aerospace applications. Comprised of a tough thermoplastic polyurethane elastomer backing combined with a high shear strength acrylic adhesive, this tape delivers exceptional resistance to scratches, tears, erosion, and punctures. The tape is qualified to aerospace specifications and is designed to help prevent structural damage to helicopter rotor blades with minimal effect on blade track and balance.
This premium protective tape is available in multiple color options including matte clear, 36118 Gray, 36173 Gray, 36251 Gray (Medium Gray), 36270 Gray, 36320 Gray, and 36375 Gray. The conformable design allows for easy application over curved surfaces and can be applied efficiently in both aircraft and rotorcraft production and maintenance environments. The tape can be painted over or applied to painted surfaces, making it versatile for various installation scenarios.
With a backing thickness of 12 mil and overall thickness of 14 mil, the 3M™ Polyurethane Protective Tape 8681HS offers superior durability and performance in demanding conditions. The acrylic adhesive adheres to a wide variety of substrates while maintaining consistent adhesion over time, yet removes easily when necessary. Operating effectively in temperature ranges from -40°C to 82°C, this tape is engineered to withstand rain, sand erosion, and other difficult environmental conditions while maintaining its protective properties.
