Highlights
- Green, 0.9 mil polyester backing. High holding power resists popping for a secure seal throughout the supply chain
- Closes packages securely without the holes, waste, sharp points and disposal of staples. Removes cleanly and remains flexible after 3 hours in autoclave, flash breaker tape, mask for acid and caustic bath
- Adhesive sticks to a variety of surfaces on contact, including fiberboard. Thin, high tear resistance, good temperature resistance, long-term aging, high strength backing
- Ideal for splicing applications on surfaces that are difficult to adhere to, such as silicone coated papers and films. Polypropylene backing withstands nicks, abrasions and moisture for long-lasting performance
For anodizing, composite bonding and splicing use 3M™ Polyester Tape 8402. 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.
Thin, Conformable Masking at High Temperatures
Our 3M™ Polyester Tape 8402 is a thin, conformable polyester tape 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. The green color makes for easier identification.
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). Our 3M™ Polyester Tape 8402 has a 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
