3M™ Acrylic Plus Tape WT4112 is a good choice for attaching EPDM/TPE components such as gaskets and seals. It features two adhesives, one on each side of a viscoelastic acrylic foam core, designed for robust performance even on complex contours and difficult automotive paint surfaces. A heat-activated adhesive forms an immediate bond to EPDM/TPE materials. Core provides stress relaxation when exposed to high application loads and maintains tight bond-line aesthetics under normal conditions.
