3M Tape Primer 94

3M Tape Primer 94 is a widely used adhesion promoter designed to significantly enhance the bonding performance of pressure-sensitive adhesives on a variety of substrates. It is especially effective on low surface energy materials such as polyethylene (PE), polypropylene (PP), and powder-coated surfaces. By increasing surface energy, Primer 94 allows tapes and films to achieve stronger, longer-lasting bonds—even in demanding industrial environments.

Features:

• • Improves bonding reliability on difficult surfaces.
  • Works with plastics, metals, glass, and painted substrates.
  • Dries quickly to support efficient production.
  • Can be applied by wipe, brush, or spray.
  • Does not affect appearance when properly applied.

Applications:

Automotive trim and emblem bonding, Electronics assembly and component fixing, Foam tape and VHB tape applications, Low surface energy plastic bonding (PP, PE), Powder-coated and painted surface preparation.
