3M™ Acrylic Foam Tape 4218P features two adhesives, one on each side of a 1.12 mm acrylic foam core, designed for robust performance and shear strength on automotive surfaces such as clear coats. The liner-side adhesive is formulated for high initial and final adhesion to rigid clear coat systems. The non liner-side works on plastics and other common trim materials.

Designed for Rigid and Many Non-Rigid Clear Coat Systems
Developed specifically for attaching exterior trim and other parts to automotive clear coat systems, our 3M™ Acrylic Foam Tape 4218P features a dark gray, 1.14 mm acrylic foam core with two different adhesives — one for each side of the application. The liner-side adhesive is excellent for bonding to automotive trim and other components. The non-liner-side adhesive is formulated for very high initial and final adhesion to scratch- and mar-resistant paint systems. The viscoelastic foam core conforms well even to complex geometries. It is engineered for stress relaxation when exposed to high stress loads, and maintains bond-line aesthetics under normal stress loads. The dark gray color of 3M™ Acrylic Foam Tape 4218P gives a pleasing bond line aesthetic. A red liner printed with the 3M logo provides easy one-piece release for efficient application.

3M recommends the use of 3M™ Automotive Adhesion Promoter 06396 for tape-to-part adhesion with 3M™ Acrylic Foam Tape 4218P on all parts, especially on plastics such as RIM, TPO, PPO, PP and PC.
