    Product Descriptions


    3M™ Acrylic Plus Tape EX4008 is a high-performance dual-adhesive acrylic foam tape, engineered for robust bonding even on complex contours and challenging automotive paint surfaces.

    Core Construction & Performance

    This 0.8 mm thick tape features a viscoelastic acrylic foam core, exclusive to 3M, that delivers excellent stress relaxation under high application loads while maintaining a tight, consistent bond line for a clean, professional aesthetic. The tape is designed with two distinct adhesives on opposite sides of the foam core, optimized for reliable, long-term attachment in automotive exterior applications.

    Key Features

    • 3M Branded Liner: The red, 3M-marked PE film liner is silicone-coated on both sides for easy one-piece release, streamlining application efficiency. It also serves as a clear authenticity marker, ensuring customers receive genuine 3M quality.
    • Liner-Side Adhesive: Formulated for exceptional initial and final adhesion to scratch-and-mar-resistant MSE automotive paint systems, delivering secure, durable bonding to vehicle exteriors.
    • Non-Liner-Side Adhesive: Engineered for strong, reliable bonding to automotive trim, moldings, and other exterior components.
    • Conformable Design: The viscoelastic foam core conforms reliably to curved, angled, and complex surfaces, ensuring consistent performance across uneven contours.
    • Inconspicuous Finish: The black tape color remains discreet after installation, ensuring high consumer satisfaction with a clean, seamless appearance.

    Ideal Applications

    • Attachment of automotive exterior trim and moldings
    • Bonding of decorative components to vehicle body panels
    • Exterior part mounting on complex contoured surfaces
    • Automotive assembly requiring durable, aesthetically pleasing bonding solutions
