3M 7100381874 Fine Line Masking Tape 19mm X 50m 64 Roll

Product Description

The 3M 7100381874 is a high-performance fine line masking tape engineered for precision two-tone paint applications in automotive OEM, specialty vehicle, and aerospace production environments. Built on a pressure-sensitive, solventless adhesive system, the tape measures 0.75 inches wide by 164 feet long per roll and carries a tape thickness of 5.2 mil. It is designed to resist lifting under high-temperature paint bake cycles and to remove cleanly with no edge residue, leaving sharp, professional paint lines. Licensed technicians, automotive painters, and aerospace finishing crews are the primary installers of this product.

This tape is suited for both simple geometric patterns and complex compound curves found on automotive fascia, custom two-tone body panels, and specialty vehicle finishing operations. Its conformability allows it to lay flat across depressed surfaces, sharp curves, and intricate contours without bridging or lifting. Each case contains 64 rolls, making it appropriate for production-volume shops as well as individual masking projects that demand consistency across multiple panels or aircraft sections.

Key Features

• Pressure-sensitive, solventless adhesive resists lifting during high-temperature paint cure cycles
• 5.2 mil tape thickness provides rigidity for clean cut lines on complex surfaces
• Removes cleanly with no edge residue for sharp two-tone paint definition
• Conforms instantly to steel, depressed areas, sharp curves, and intricate surface geometry
• Suitable for automotive OEM, specialty vehicle, and aerospace masking applications
• Case pack of 64 rolls supports production-volume finishing operations

Compatibility

Designed as a precision masking tape for automotive OEM paint lines, specialty vehicle finishing, and aerospace surface preparation where high-temperature resistance and clean removal are required.

Installation Notes

Apply to clean, dry, and dust-free surfaces before masking. Ensure substrate is free of oils, wax, or release agents that could compromise adhesion and allow paint bleed. Remove the tape promptly after painting while the finish is still warm but not fully cured, pulling back at a low angle to maintain a clean edge. Follow facility safety and environmental guidelines when working with paint systems and solvents in the surrounding application area.
