Effectively Mask in High Temperature Applications
3M™ Polyester Tape 8991 is a general purpose, thin, conformable polyester tape ideal for masking in high temperature applications. 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.
With good chemical resistance, this tape works effectively in chemical processes and demanding work conditions, such as anodizing. The pressure sensitive silicone adhesive performs under a broad range of temperatures ranging from -60°F (-50°C) to 400°F (204°C).
Recommended applications
- Masking parts for high temperature powder coat painting
- Holding parts or vacuum bags during composite bonding operations
- Masking metal surfaces in acid or caustic chemical milling baths
- Protective tape reduces scratches during handling and shipping
