- Provides erosion protection to help reduce maintenance cost
- Tough, thermoplastic polyurethane elastomer is abrasion, scratch, erosion, tear and puncture resistant
- Dual liner helps improve installation process by acting as an installation aid during maintenance intervals and monument installation
- Acrylic adhesive bonds to a wide variety of substrates and retains bond strength over time, yet removes easily when needed
3M Polyurethane Protective Tape 8663DL is an erosion protection tape and primarily used on aircraft leading edges such as vertical stabilizers. It is constructed of a polyurethane backing coated with a long-aging, solvent-resistant, pressure sensitive adhesive that is protected with a transparent easy-release dual liner that also helps achieve precise installation.
3M Polyurethane Protective Tape 8663DL is a transparent 18 mil, polyurethane elastomer tape designed to protect leading edges such as vertical stabilizers against rain and sand. Our tough polyurethane backing is scratch, tear, erosion, puncture and impact resistant. The transparent tape can be painted or applied over painted surfaces. This tape has excellent environmental resistance properties and has been used to isolate and protect substrates from environmental damage and erosive elements. The bottom 3 mil polyethylene liner protects the adhesive from contamination prior to application. The top liner is imprinted with black lines at four inch intervals aids in precise installation. 3M Polyurethane Protective Tape 8663DL is qualified to leading aircraft manufacturer specifications for protection from sand and rain erosion.
