3M 966

Main features

  • Up to 232 deg C Short-Term Exposure
  • 10,000-Minute Static Shear
  • Metal and High-Energy-Plastic Bonding

Product Description

3M™ Adhesive Transfer Tape 966 is a 2.3 mil (0.06 mm) adhesive transfer tape featuring 3M™ High Temperature Acrylic Adhesive 100 on a 62# densified kraft liner. It provides excellent bonding to metals and high-surface-energy plastics, exceptional static shear performance at elevated temperatures, and resistance to demanding chemical and environmental exposure. Its low-outgassing and low-leachable-chloride characteristics make it suitable for evaluated electronic, aerospace, industrial labeling, nameplate, and die-cutting applications.

Key features

  • High-temperature performance: Supports short-term exposure up to 232°C (450°F) and long-term exposure up to 204°C (400°F).
  • Exceptional static shear: Achieves 10,000-minute static shear results at temperatures from 23 to 232°C under the published test conditions.
  • Strong high-surface-energy bonding: Provides excellent adhesion to metals and good adhesion to high-surface-energy plastics.
  • Environmental and chemical resistance: Resists humidity, water, UV exposure, temperature cycling, gasoline, oil, mild acids, and mild alkalis when properly applied.
  • Low-outgassing construction: Offers low outgassing and low leachable chloride for evaluated electronic and aerospace applications.

Applications / Suitable for

  • Bonding metal nameplates
  • High-temperature labels and identification components
  • Die-cut parts requiring a densified kraft liner
  • Evaluated electronic, aerospace, and industrial applications
