3M™ polyester tape. 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. 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).
