May, 2017
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.
