3M™ Acrylic Plus Tape EX4311 features an acrylic adhesive formulated for bonding to advanced clear coat systems including carbamates. The non-liner side features a different adhesive for a range of paint and LSE surfaces. The 1.14 mm viscoelastic foam core provides stress relaxation when exposed to high application loads, and maintains tight bond-line aesthetics under normal conditions.
Developed for Adhesion to the Latest Automotive Clear Coat Systems
Part of the 3M™ Acrylic Plus Tape Series EX4300 series developed specifically for attaching exterior trim and other parts to low surface energy (LSE) automotive paint surfaces, our 3M™ Acrylic Plus Tape EX4311 features a 1.14 mm acrylic foam core with two different adhesives – one for each side of the application. The liner-side adhesive is formulated for bonding to the most advanced LSE automotive clear coats, including those comprised of epoxy/acid powder, 2K urethane, acrylosilane and MVSS carbamate. This adhesive is also excellent for existing medium surface energy (MSE) paint systems. The non-liner-side adhesive is formulated for high initial adhesion to a variety of automotive substrates and coatings. 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 inconspicuous black color of 3M Acrylic Plus Tape EX4311 helps ensure higher satisfaction among consumers.
The red, 3M branded liner is silicon-coated on both sides for easy one-piece release and efficient tape application. The 3M branded liner features a subtle 3M logo-marking to signify true 3M performance - easy to identify, and difficult to imitate. This proprietary branding technology is designed for fast, easy identification of 3M™ Acrylic Foam Tapes.
Better Science for Better Adhesion from 3M
Since 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. All of it goes into each of our products developed for automotive OEMs and Tiers, like 3M™ Acrylic Plus Tape EX4311.
