Performance in Demanding Conditions
3M Polyester Tape 8902 is a thicker, more durable polyester tape ideal for masking in high temperature applications and adheres well to silicone coated surfaces. The translucent blue backing is tear resistant. Coated with a silicone adhesive, this tape functions well in masking for powder coating to provide sharp paint lines. It removes cleanly and in one piece from most surfaces, avoiding slivering and breaking. This tape also excels in permanent splicing operations on silicone liners, papers and films subject to high temperatures.
With good chemical resistance, this tape works effectively in chemical processes and 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 400°F (204°C).
Masking parts for high temperature powder coat painting
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
