Product Description

3M™ Double Coated Tape 93020LE is a high-strength adhesive tape featuring 3M™ High Strength Acrylic Adhesive 300LSE, designed to provide excellent bond strength to a variety of substrates, including low surface energy plastics such as polypropylene and powder-coated paints. It also adheres well to surfaces contaminated with oil, typically found in machine parts​.


Key Features

  • High bond strength to most surfaces, including low surface energy plastics and powder-coated paints.
  • Excellent adhesion to surfaces contaminated with machine oil.
  • Polyester film carrier provides dimensional stability and improves handling during slitting and die-cutting.
  • Bond strength increases over time and with temperature exposure.
  • Very high initial adhesion ensures quick and reliable bonding​.

Recommended Applications

  • Consumer electronic device assemblies such as phones, tablets and wearable devices
  • Industrial electronic device assemblies such as workstations
  • Plastic assembly bonding in a variety of industries
  • Various assemblies in the automotive industry
  • Application and assembly of components on appliances
  • Medical equipment and device fabrication
  • General industrial applications such as trim attachment​
