Scotch Fine Line Tape 218 is a high-performance polypropylene plastic tape that's ideal for painting long straight lines and sweeping curves with crisp, sharp edges and excellent color line separation. It's often used as a layout tape for high-value multicolor or custom-painted graphics. Features a natural rubber pressure adhesive capable of delivering the high instant adhesion necessary for critical large-scale paint applications. The polypropylene backing is stiffer than vinyl fine line tapes but still conforms easily around corners. Features good moisture and solvent resistance and resists heat in bake cycles that reach 250F/121C for up to 30 minutes. Prevents soak-in and edge lifting. Use for fine line paint masking or specialty vehicle, marine and aerospace paint jobs.
