3M Adhesion Promoter 111

3M Adhesion Promoter 111 (AP111) is a high-performance surface treatment designed to enhance the adhesion of pressure-sensitive adhesives on low surface energy (LSE) materials. It is particularly effective on plastics such as polypropylene (PP), polyethylene (PE), and ABS, where bonding is typically difficult. By increasing surface energy and improving adhesive wet-out, AP111 enables stronger, more reliable bonds, especially in demanding industrial and automotive applications.

Features:

• • Excellent performance on PP, PE, and similar substrates.
  • Enhances bonding of tapes and films.
  • Reduces processing time.
  • Does not affect surface appearance.
  • Apply by wipe, brush, or spray.

Applications:

Automotive trim and interior parts, Electronics and plastic component assembly, Appliance manufacturing, Foam tape and VHB tape bonding, Plastic surface preparation before taping.
