Premium dual-adhesive automotive foam tape with 0.76mm acrylic core for exterior trim attachment, featuring silicone-coated polyethylene liner and stress-relaxation properties for complex contours.
3M™ Acrylic Plus Tape EX4008T is a premium dual-adhesive foam tape specifically engineered for automotive exterior trim attachment. This innovative product features two different adhesives applied to a durable 0.76mm black acrylic foam core, with each side optimized for specific paint systems. The liner side adhesive is designed for bonding to rigid clear coat systems, while the non-liner-side adhesive provides exceptional initial adhesion to powder-coated paints and modern automotive finishes. The conformable closed-cell foam core delivers superior stress relaxation under high application loads while maintaining tight bond-line aesthetics under normal conditions.
Developed specifically for attaching automotive exterior trim parts such as stone chip moldings, fender moldings, wheel arch extensions, roof ditch moldings, and side body moldings, this tape adapts exceptionally well to complex contours and difficult paint surfaces. The polyethylene T-liner is silicone-coated on one side, making it suitable for heat-bonding and other PSA tabbing methods. The inconspicuous black color ensures high satisfaction among consumers and maintains professional appearance. With over a century of adhesive innovation since 1925, 3M has engineered this product to meet stringent OEM specifications including WSS-M11P65-A2, MS-12194, and GMW15201 Type IXA.
The 3M branded red liner features silicon coating on both sides for easy one-piece release and efficient tape application, with subtle 3M logo-marking to signify authentic 3M performance and ensure easy identification. This proprietary branding technology makes it difficult to imitate and provides fast, easy identification of genuine 3M Acrylic Foam Tapes. The product is backed by comprehensive technical support and access to 3M specialists for application advice and optimization.
