  • Works in demanding conditions and retains flexibility in autoclave conditions in temperatures ranging from -6°F (-5°C) to 35°F (177°C)
  • Silicone adhesive provides clean removal from a variety of surfaces
  • Chemical resistant adhesive and backing provide durability in difficult environments such as anodization
  • Retains flexibility in autoclave conditions in temperatures ranging from -60°F (-50°C) to 350°F (176°C)
  • Ideal for splicing applications on surfaces that are difficult to adhere too, such as silicone coated papers and films
  • Translucent green backing is easily identifiable for splicing applications
  • Waterproof and easily removable

For anodizing, composite bonding, and splicing, use 3M™ Polyester Tape 8403. This translucent-green tinted tape is coated with a silicone adhesive that bonds well on difficult surfaces, including silicone coated papers and films. It is chemical resistant and performs under a wide range of temperatures and environments. This tape is a thicker version of 3M™ Polyester Tape 8402.

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. Dispensable and appropriate for outdoor use.

Suggested Applications

  • Splicing of silicone liners, films and papers
  • Holding parts or vacuum bags during composite bonding operations
  • 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
