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). The 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
