3M 8901 Features

  • Works in demanding conditions and high temperatures ranging from -60ºF (-50ºC) to 400ºF (204ºC)
  • Clean removal during high-temperature masking operations such as powder coating
  • The polyester film offers excellent thermal and chemical resistance while maintaining flexibility
  • Silicone adhesive provides clean removal from a variety of surfaces
  • Translucent blue backing provides easy identification and positioning
  • Polyester films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility.
  • Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing, and adhesive transfer.
  • Silicone adhesives adhere well to tough-to-stick-to surfaces like silicone liners and fixtures coated with mold release.
  • Removes cleanly from stainless steel, anodized aluminum, and glass after 5 hours. bake cycle at 350°F (177°C).
  • A variety of tape thicknesses offered allows uses for multiple applications.

3M 8901 Applications

  • Masking parts for high-temperature powder coat paint
  • Splicing of silicone liners, films, and papers
  • Holding parts or vacuum bags during composite bonding operations
  • Masking metal surfaces in acid or caustic chemical milling baths
  • Protective tape reduces scratches during handling and shipping
  • Splicing of silicone-treated webs.
  • Masking parts for powder coat paint
  • Holding parts or sealing vacuum bags during processing
  • Masking edges of overlap seams in metal bonding process where excess adhesive flows onto tape. Minimizes clean-up on tape removal.
  • Composite bonding – sticks well to molds treated with a release agent, works as a flash breaker tape on the removal of the part from the mold, and seals vacuum bags if vacuum bag treatment is part of the process.
  • Provides a good barrier to the separation of dissimilar metals.
  • Holding silicone or silicone treated parts.
  • Cutting or slitting to the length and width required by the customers
  • Laminate liner or other materials
  • Die cut according to customer's drawing
