Professional-grade high-temperature nylon film tape with non-silicone rubber adhesive, rated to 400°F, ideal for composite bonding, masking, and metal applications with clean removal properties.
3M™ High Temperature Nylon Film Tape 855 is a specialized industrial adhesive tape engineered for demanding high-temperature applications requiring non-silicone adhesive solutions. This 3.6 mil thick tape features a robust rubber adhesive formulation on a tough nylon backing that applies easily, removes cleanly, and withstands short temperature bake cycles up to 400°F (204°C) without leaving residue. The non-silicone rubber adhesive eliminates the problematic residue that silicone-based adhesives typically leave behind, resulting in faster cleanup times and ensuring superior anchorage for subsequent adhesives and paints.
Designed specifically for advanced composite and metal bonding applications, this tape maintains exceptional adhesion and removes cleanly after exposure to 350°F (177°C) for extended periods and following shorter exposure to bake cycles up to 400°F (204°C). The nylon backing provides superior toughness and high elongation properties at 460%, making it ideal for effective masking, composite bagging operations, and efficient removal of flashing after composite bonding. Each roll measures 1/4 inch wide by 72 yards long, and the case contains 144 rolls for bulk purchasing convenience.
This tape is engineered for industrial and occupational use in automotive manufacturing, general industrial applications, military and government operations, and transportation sectors. The white nylon backing provides excellent visibility during application and removal processes. With an 18-month shelf life from date of manufacture and meeting ASTM D3330, ASTM D3652, and ASTM D3759 specifications, this tape delivers reliable performance for critical bonding and masking applications where temperature resistance and clean removal are essential requirements.
