Brands: 3M

Available size: 1.1 mm (45 mil) and 1.52 mm (60 mil) calipers

Shelf Life: 2 years

3M™ Acrylic Plus Tape Series EX4500 is a series of deep black, double-coated acrylic foam tapes designed for the attachment of automotive exterior trim parts – without the use of adhesion promoter.

3M series EX4500 tapes offer an advanced adhesive system – on both sides of the product – that adheres well to traditional, medium surface energy, and scratch- and mar-resistant automotive paint and polymer systems.

Typical applications: pillars, garnishes, nested components and window visors, and other aftermarket accessories.

Product Features

  •  Primerless adhesion capability – allowing for adhesion to medium surface
    energy plastics without the use of adhesion promoter on both liner and
    non-liner sides of the product.
  • Excellent adhesion to traditional, low surface energy, and scratch and mar
    resistant automotive paints.
  • Unique foam core that provides stress relaxation when high application
    loads are encountered, while maintaining tight bond-line aesthetics under
    normal conditions.
  • Deep black color which provides excellent bond-line appearance.
