Premium transparent polyurethane protective tape for aircraft erosion protection with 18 mil thickness, pressure-sensitive acrylic adhesive, and exceptional abrasion resistance. Ideal for leading edges and high-wear aerospace applications.
3M™ Polyurethane Protective Tape 8663 is a premium erosion protection tape specifically engineered for aircraft leading edges such as vertical stabilizers, wings, and control surfaces. This transparent 18 mil polyurethane elastomer tape provides exceptional protection against rain, sand, and environmental erosion while maintaining structural integrity. The tape is constructed with a tough, thermoplastic polyurethane backing that delivers superior abrasion, scratch, erosion, tear, and puncture resistance, making it ideal for high-wear applications in aerospace environments.
The tape features a long-aging, solvent-resistant, pressure-sensitive acrylic adhesive protected by a transparent easy-release liner. This advanced adhesive formulation bonds effectively to a wide variety of substrates including bare metal, painted surfaces, and composite materials, while retaining exceptional bond strength over extended periods and through various climate and temperature changes. The transparent nature of the tape allows for easy application and conforms smoothly over curved surfaces, and it can be painted or applied over existing paint without compromising performance.
Qualified to leading aircraft manufacturer specifications, this protective tape helps reduce maintenance costs, extends service life, and prevents beam corrosion. Airlines worldwide rely on 3M Polyurethane Protective Tapes to enhance operational efficiency, reduce process times, and lower overall aircraft maintenance burden. Each case contains 2 rolls of 36-yard length tape at 4 inches width, providing comprehensive coverage for aircraft protection applications.
