Product Description

Scotch Fine Line Tape 218 is a green polypropylene-film fine-line masking tape for producing crisp paint edges on straight lines and sweeping curves. Its natural-rubber pressure-sensitive adhesive provides high instant adhesion, while the low-profile backing supports color separation and conforms around corners. The tape resists most solvents and moisture and withstands bake cycles up to 121 deg C for 30 minutes. Typical construction values include 0.13 mm total thickness, 720% elongation at break, and 22.8 N/cm tensile strength. It is used for fine-line masking in specialty vehicle, automotive, rail, marine, aerospace, two-tone, multicolor, and custom graphic finishing.

Key features

  • Crisp color separation: The low-profile backing and high adhesion support sharp paint lines on straight and sweeping layouts.
  • Solvent and moisture resistance: The tape resists most solvents and moisture during supported paint-finishing work.
  • Bake-cycle capability: The applied tape withstands bake cycles up to 121 deg C for 30 minutes.

Applications

Applications include fine-line paint masking, two-tone and multicolor layouts, custom graphics, and specialty vehicle, automotive, rail, marine, and aerospace finishing.

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
720 %
Tensile Strength (Thin Film)
Tensile strength determines the resistance of a material to break under tension and it measures how much elongating load (or tensile stress) it can handle before fracture. To make it simple, it measures how much force we have to apply when pulling apart a material before it breaks.
