Dual-adhesive acrylic foam tape with 0.76 mm core for automotive trim attachment to clear coat systems. Features excellent conformability, stress relaxation, and plasticizer resistance for reliable performance.
3M™ Acrylic Foam Tape 5314 is a specialized dual-adhesive foam tape engineered for automotive exterior applications. Featuring a gray, closed-cell 0.76 mm acrylic foam core, this tape delivers exceptional stress relaxation under load while maintaining bond-line aesthetics. The innovative dual-adhesive design includes a liner-side adhesive formulated for high initial and final adhesion to rigid automotive clear coat systems, and a non-liner-side adhesive optimized for bonding to automotive trim materials and plastic components. The viscoelastic foam core exhibits excellent conformability to complex geometries and maintains structural integrity under normal stress conditions.
Developed specifically for attaching exterior trim, body side moldings, roof slats, and other components to rigid clear coat systems, this tape represents decades of 3M adhesive technology innovation. The gray color provides an aesthetically pleasing bond line, while the red 3M branded liner ensures easy one-piece release for efficient application. The tape is engineered for excellent plasticizer resistance and performs reliably across a wide range of automotive trim materials including RIM, TPO, PPO, PP, and PC plastics.
3M recommends using 3M™ Adhesion Promoter with this tape for optimal tape-to-part adhesion, particularly on plastic components. The proprietary 3M branding on the liner helps customers identify authentic 3M products and provides evidence of quality. With its robust performance characteristics and proven track record in automotive OEM applications, 3M™ Acrylic Foam Tape 5314 delivers confidence and reliability for demanding automotive bonding requirements.
