Information
The 3M?Polyester Tape?8403 is specifically engineered for aerospace applications where composite panels or metallic structures undergo high temperature cure, anodising, or splicing operations. Its polyester film backing and silicone adhesive provide clean removal and durability in autoclave cycles up to ~177?°C (~350?°F). The green tinted backing aids visual identification on the shop floor. Aircraft engineers use this tape for composite manufacture and repair, sealing vacuum bagging, protecting surfaces during chemical treatment and masking for powder coating/painting operations. Its balance of thin film construction and durability makes it ideal for low profile masking tasks in advanced aerospace fabrication.
