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.
3M™ Polyester Silicone Adhesive 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 colour makes for easier identification. Dispensable and appropriate for outdoor use.
Suggested 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
