3M 950

Main features

  • 5 mil Adhesive 300 Construction
  • High Initial Adhesion and Holding
  • Multi-Substrate Pressure-Sensitive Bonding

Product Description

3M™ Adhesive Transfer Tape 950 is a 5 mil (0.13 mm) adhesive transfer tape featuring 3M™ Adhesive 300, a pressure-sensitive, medium-firm, fibered acrylic adhesive supplied on a tan 60# glassine liner. It provides very high initial adhesion with good holding power across a range of materials, including metals, foams, fabrics, coated papers, and high- and low-surface-energy plastics.

Key features

  • High initial adhesion: 3M™ Adhesive 300 provides strong initial bonding with good holding power.
  • Broad substrate compatibility: Bonds to metals, foams, fabrics, coated papers, and high- and low-surface-energy plastics.
  • Conformable 5 mil adhesive: The 0.13 mm adhesive thickness supports bonding to surfaces where texture may be visible.
  • Environmental resistance: Provides resistance to humidity, water, UV exposure, temperature cycling, oil, mild acids, and mild alkalis when properly applied.
  • UL-recognized construction: Recognized under UL 969 for Marking and Labeling Systems Materials Components.

Applications / Suitable for

  • Bonding graphic nameplates and overlays
  • Attaching metal nameplates and rating plates
  • Laminating foam for gasket applications
  • Joining similar and dissimilar industrial materials
