The 3M™ Acrylic Plus Tape Series EX4500 is engineered for primerless application of trim components in automobiles. The EX4500 offers strong adhesion to medium surface energy substrates, meaning these products will bond with a wide variety of paints without pre-treatments. Specifically, the proprietary technology in the EX4500 series bonds with acrylic, acrylonitrile butadiene styrene (ABS), acrylonitrile ethylene styrene (AES), acrylonitrile styrene acrylate (ASA), polycarbonate (PC), and PC+ABS, as well as paints composed of carbamate, epoxy / acid powder and 2K urethane. This removes cost, health and safety concerns, and the environmental impact of using primers for bonding on these materials. EX4500 tapes come in deep black to conceal bond lines and create a durable and polished appearance. The tapes are ideal for pillar garnishes, body-side moldings, step plates, vent visors and chrome appliques.
