3M 7100028502 Fine Line Masking Tape 5.0 Mil Green

Product Description

The 3M 7100028502 is a green, film-backed fine line masking tape engineered for high-precision paint line work and general masking applications across automotive, industrial, and finishing trades. The tape runs 2.25 inches wide by 60 yards long at a 5.0 mil total thickness, delivering a low-profile edge that resists paint bleed and produces clean, sharp color separation. Adhesion to steel measures 37 oz. per inch of width, and tensile strength reaches 13 lbs. per inch of width. The specialty-processed film backing stretches to follow smooth curves without lifting or wrinkling, making it suitable for both long straight runs and contoured surfaces.

This tape is used in automotive body shops, paint booths, industrial finishing lines, and manufacturing environments where a precise, clean paint line is required. The film backing can be applied over freshly painted surfaces sooner than conventional paper tapes, reducing cycle time and minimizing the risk of imprint damage to underlying coatings. It also performs well in general masking and holding applications where moisture or solvent exposure is a concern. This product is intended for indoor use only and should not be subjected to prolonged outdoor exposure.

Key Features

• 5.0 mil total thickness for low-profile edge and clean paint line separation
• Film backing stretches for smooth curves and contoured surfaces
• 37 oz. per inch adhesion to steel for secure hold during painting
• 13 lbs. per inch tensile strength resists tearing during removal
• Excellent moisture and solvent resistance during masking operations
• Can be applied over fresh paint sooner than paper tapes, reducing imprint risk

Compatibility

Designed for use as a fine line masking tape in automotive refinishing, industrial coating, and general-purpose masking applications where a precise paint edge and film-backed flexibility are required.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and contaminants to ensure proper adhesion. Remove the tape promptly after painting while the coating is still slightly soft to achieve the cleanest paint edge and reduce the risk of coating lift. Do not expose this tape to outdoor environments or direct UV. Handle the roll carefully to avoid stretching the backing before application.
