3M™ Polyimide Tape 8997 is an amber colored polyimide tape with silicone pressure sensitive adhesive. Tape construction is ideal for applications that may require high temperature, chemical, and abrasion resistance with the
benet of transparency.

FEATURES

Polyimide films offer excellent thermal, abrasion, and chemical resistance while maintaining their flexibility.
Amber color makes tape placement obvious for both application and removal.
Thin backing leaves a sharp paint line and some conformability.
Silicone adhesives offer high heat resistance compared to many rubber and acrylic adhesives, reducing failure due to softening, oozing, and adhesive transfer.
Silicone adhesive removes cleanly from many surfaces.
Linered version available for die-cuts.

APPLICATIONS

Masking parts for powder coat painting.
Masking edges of overlap seams in metal bonding process where excess adhesive ows onto tape. Minimizes clean-up on tape removal.
Provides a good barrier for separation of dissimilar metals.
