Premium 18 mil polyurethane protective tape for aerospace erosion protection with high shear acrylic adhesive, exceptional tear and puncture resistance, conformable to curved surfaces, qualified to aerospace specifications.
3M™ Polyurethane Protective Tape 8681HS is a premium 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 advanced protective tape features excellent conformability, allowing it to easily apply and conform over curved surfaces commonly found in aircraft and rotorcraft components. The acrylic adhesive adheres to a wide variety of substrates while retaining constant adhesion over time, yet removes easily when necessary. The tape can withstand difficult environmental conditions including rain and sand erosion, making it ideal for both production and maintenance applications in demanding aerospace environments.
Available in light gray (36320) and multiple other color options including matte clear and various gray shades, the 3M 8681HS tape comes in 6 inch width by 36 yard length rolls, with 2 rolls per case. This product can be painted over or applied to painted surfaces, providing versatile protection for critical aerospace components. The tape's durability and reliable performance have made it a trusted choice among aerospace professionals worldwide.
