  1. What is 3M™ Polyimide Tape 8997?

    3M™ Polyimide Tape 8997 is a specially designed tape that can withstand high temperatures of up to 500°F (260°C). It is commonly used in electrical and electronic applications for insulation, mask-off for gold plating, fiber optics cables, automotive sensor components, etc.

  2. What are the dimensions of this tape?

    The dimensions of the light amber-colored polyimide tape are as follows- length = 36 yards (32.9 meters), width = 2 inches (5.08 cm), thickness or Mil strength =2.2 mils and it comes in a case containing 24 rolls.

  3. Why should I choose this particular product over other options available?

    This is an excellent choice compared to other high-temperature tapes because of its ability to peel off cleanly even after being subjected to high heat environments without leaving any sort of adhesive residue behind which can damage your products.

  4. Where do you recommend using this type of speciality tape?

    We recommend using our Polyimide tapes on surfaces that will be exposed to extremely hot temperatures while requiring long-term durability and resistance against solvents like chemicals or cleaning agents. Some example applications include printed circuit board fabrication, wire harnesses during soldering operations and surface protection from molten solder splash on transformers/coils.

Economical, Reliable, High Temperature Powder Coat Masking

As temperatures continue to rise in powder coat paint operations, it is important to have a masking tape that can withstand the heat. 3M™ Polyimide Tape 8997 is specifically designed for higher temperature powder coat paint applications. It features a 1.0 mil thick polyimide backing with a 1.4 mil silicone adhesive, making it ideal for use in high temperature applications up to 500°F/260°C. The tape's light amber color ensures easy identification and alignment. Additionally, the high dimensional and tensile strength of this polyimide tape allows it to break through cured paint without silvering or tearing.

Common uses for 3M™ Polyimide Tape 8997 include masking parts for powder coating, masking edges of overlap seams, e-coating, electroplating, anodizing, and as a barrier of separation for dissimilar metals. It resists shrinking, curling, and edge lifting and removes with zero adhesive residue. The thin, flexible backing seals tight on contact, peels off clean, and leaves sharp, clear paint edges.

Recommended Application
  • Masking parts for powder coating
  • Masking edges of overlap seams
  • Barrier of separation for dissimilar metals
Polyimide Tapes for High Temp Applications

3M, the leader in masking tape technology, has developed a variety of polyimide tapes to insulate, mask, protect, seal, flash break, tab, powder coat, and anodize mask. These revolutionary polyimide tapes withstand heat during rigorous, high-temperature masking operations. An exceptionally thin backing resists tears, abrasion, and the effects of aging. Choose a tape that can take the heat and keep your paint lines sharp!
