3M 7000123346 Fine Line Masking Tape 5.0 Mil Green

Product Description

The 3M 7000123346 is a green, film-backed fine line masking tape engineered for sharp paint line separation and precision masking work. The tape measures 0.375 inches wide by 60 yards long at a 5.0 mil thickness, which contributes directly to clean, low-profile edges with minimal paint bleed. The specially processed film backing stretches to follow smooth curves without lifting or wrinkling, while maintaining straight-line integrity on flat panels. Adhesion to steel is rated at 37 ounces per inch of width, and tensile strength reaches 13 pounds per inch of width. Auto body technicians, painters, and finishing crews use this tape where precise color separation is required on both fresh and cured surfaces.

This tape is suited for automotive refinishing, custom paint work, and precision masking in body shops and manufacturing environments. The film backing allows earlier removal over fresh paint compared to standard paper masking tapes, reducing the risk of surface imprint damage. It performs in temperature conditions up to 250 degrees F and provides solid resistance to moisture and solvents encountered in spray booth environments. It is not rated for outdoor or prolonged UV exposure and should be removed promptly after the masking operation is complete.

Compatibility

Designed for use in automotive refinishing and precision masking applications where a thin, flexible film-backed tape is required for clean paint line separation on curved and flat surfaces.

Installation Notes

Surface should be clean, dry, and free of dust or oils before tape application. Apply with firm, even pressure to ensure full contact along the tape edge. Remove the tape at a low angle promptly after painting or once the paint has reached the appropriate cure stage to avoid lifting or imprint damage. This tape is not intended for outdoor or extended UV exposure.
