Information
3M™ Polyurethane Protective Tape 8663 / 8663 DL
Overview
3M™ Polyurethane Protective Tape 8663 is a transparent, abrasion-resistant polyurethane protective film designed to protect aerospace and industrial surfaces from erosion, corrosion, abrasion, punctures, tearing, and minor impact damage. Formulated with excellent ultraviolet resistance and a long-aging acrylic pressure-sensitive adhesive, the tape provides a durable protective barrier that can be applied quickly with minimal tools. The 8663 DL version incorporates dual liners to facilitate complex installations and aircraft floor corrosion protection applications.

Material Engineering & Design Features
3M™ 8663 utilizes a high-performance polyurethane elastomer engineered to withstand harsh environmental exposure while maintaining flexibility and transparency. The durable film acts as a sacrificial protective layer that absorbs wear and erosion before damage can occur to the underlying substrate.
Typical mechanical properties include:
- Tensile Strength: 2049 N/100 mm (117 lb/in)
- Elongation at Break: 500%
- Peel Adhesion to Bare Aluminum: 92 N/100 mm (84 oz/in)
- Peel Adhesion to Acrylic Enamel Paint: 61 N/100 mm (56 oz/in)
- Peel Adhesion to ABS Plastic: 71 N/100 mm (65 oz/in)
The 8663 DL configuration incorporates dual removable liners, including a polyester top liner that increases stiffness during installation and serves as an application aid for complex geometries.
