June, 2011
3M™ Polyester Tapes 8901, 8902, and 8905 are all made with strong polyester backing and
silicone adhesive, allowing them to be used in applications requiring high temperatures or
adhesion to silicone treated surfaces. This tape family offers a range of backing thickness to
accommodate application needs from thin tape for splicing to a thicker, stronger tape from
pulling through flashing or multiple layers.

Features
• 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 a 5 hour.
bake cycle at 350°F (177°C).
• Variety of tape thicknesses offered allows uses for multiple applications.
Application Ideas
• Splicing of silicone treated webs.
• Masking parts for powder coat painting
• 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.

bag treatment is part of the process.
• Provides a good barrier for separation of dissimilar metals.
• Holding silicone or silicone treated parts.
