3M™ 8402 Polyester Tape, 1"W x 72 Yards, 1.9 Mil, Green - Pkg Qty 36

Product Description
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 :
  • 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
Features:
  • Works in demanding conditions and retains flexibility in autoclave conditions
  • Chemical resistant adhesive and backing provide durability in difficult environments, such as anodization
  • Ideal for splicing applications on surfaces that are difficult to adhere to, such as silicone coated papers and films
  • Translucent green backing is easily identifiable for splicing applications
  • Meets several aerospace specifications
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.
