  1. What kind of tape is the 3M™ Polyester Tape 8403?

    The 3M™ Polyester Tape 8403 is a pressure-sensitive tape, which means that it becomes sticky when it's pressed onto a surface.

  2. How wide and how long is each roll of this tape?

    Each roll of the 3M™ Polyester Tape 8403 measures at 14 inches in width and has a length of up to 72 yards.

  3. Is this particular type of tape easy to tear by hand or does it require scissors?

    This polyester tape by 3M is designed in such a way that you can easily cut it either by using scissors or tearing them with your hand - whichever method suits you better!

  4. What makes this green-colored version different than other colored options available on the market?

    . Although color can be used as an identification tool for certain types of devices, what mainly sets this green-colored option apart from others is simply its appearance.

  5. .: Can the adhesive leave residues once removed after some time.

    .: No, our specially formulated adhesive holds strong during application yet comes off cleanly upon removal without leaving any residue behind.

Thick and Durable Tape for Masking in High Temperatures

3M™ Polyester Tape 8403 is a thicker polyester tape designed for easy handling and more durability. It is ideal for masking in high temperature applications and adheres well to silicone coated surfaces. The tape has a silicone adhesive that functions well for masking and removes cleanly, in one-piece, from most surfaces. This tape also excels in permanent splicing operations on silicone liners, papers and films subject to high temperatures.

With exceptional chemical resistance, this tape works effectively in some of the most demanding work conditions, such as anodization. The pressure sensitive silicone adhesive performs under a broad range of temperatures ranging from -60°F (-50°C) to 425°F (218°C). 3M™ Polyester Tape 8403 has long service life and is designed to remain firmly adhered and flexible.

Recommended Applications
  • 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
  • Flash breaker in metal bonding processes where the excess epoxy (flash) flows on the tape
  • Protective tape reduces scratches during handling and shipping
  • Paint mask for areas subject to higher temperature bake cycles
