3M™ Acrylic Foam Tape 5403

3M™ Acrylic Foam Tape 5403 is an automotive attachment tape for attaching gasket and weatherstrip seals in automotive applications. It features a heat-activated adhesive on an 0.8 mm viscoelastic acrylic foam core. The adhesive creates an immediate, durable bond to EPDM/TPE and many Santoprene® TPV materials. The liner-side adhesive is designed specifically for bonding to high-solids clearcoat systems. The conformable foam core provides excellent wet-out for automotive weatherstripping and gasket seals.

Featuring a gray, 0.8 mm acrylic foam core, 3M™ Acrylic Foam Tape 5403 has an extremely strong heat-activated adhesive formulated for an immediate, consistent and durable bond to EPDM/TPE materials. This adhesive delivers high initial tack, rapid build and excellent final adhesion without the use of an adhesion promoter, and resists temperatures up to 203 °F / 95 °C for efficient application prior to seal-coating bakes. The adhesive is applied to the non-liner side of an 0.8 mm acrylic foam core designed to help maintain seal integrity. The viscoelastic core on this automotive sealing tape provides excellent wet-out as well as stress relaxation when exposed to high application loads. The adhesive applied to the liner side of the core is made for high initial and final bond to automotive trim and part materials. This adhesive is great for plastics with plasticizers as well as traditional and newer automotive paints including rigid clearcoat systems, and may also be compatible with ABS, PC and many flexible clearcoats. The polyethylene liner is silicone-coated on one side, good for heat-bond tabbing.
