3M 7100107031 Fine Line Masking Tape 5.0 Mil 3in X 60yd

Product Description

The 3M 7100107031 is a green, film-backed fine line masking tape designed for precision paint masking, color separation, and general holding applications. At 5.0 mils thick, the tape lays flat with a low profile that produces clean, sharp paint lines. The specially processed film backing stretches readily, allowing smooth application around curves and contours without lifting or wrinkling. Adhesion to steel is rated at 37 oz. per inch of width, and tensile strength reaches 13 lbs. per inch of width. Licensed painters, auto body technicians, and industrial finishing crews use this tape where edge definition is critical.

This tape is suited for automotive refinishing, industrial paint lines, and detail masking work where both straight runs and curved sections must be taped in a single pass. The film backing resists moisture and solvents, making it stable during spray and dip operations. It can be applied over freshly painted surfaces sooner than conventional paper masking tapes, reducing the risk of imprint damage to the underlying finish. Each roll measures 3 inches wide by 60 yards long, sold individually.

Key Features

• 5.0 mil film backing delivers low profile for tight paint line definition
• Stretches smoothly for curves and contoured surfaces without tearing
• Adhesion to steel: 37 oz. per inch of width
• Tensile strength: 13 lbs. per inch of width with 720 percent elongation at break
• Resistant to moisture and solvents during finishing operations
• Safe for use over fresh paint with reduced risk of imprint damage compared to paper tapes

Compatibility

Designed for use as a precision masking tape in automotive refinishing, industrial coating, and general paint-line applications where a thin, conformable film backing is required.

Installation Notes

Apply to clean, dry, and dust-free surfaces for best adhesion and edge seal. Do not expose this tape to outdoor or prolonged UV conditions, as it is not rated for exterior weathering. Maximum use temperature is 250 degrees F; do not exceed this threshold in bake or cure ovens. Remove the tape promptly after the finishing process is complete to avoid adhesive transfer to the substrate.
