3M 7000124099 Fine Line Tape 215 Blue 2in X 60yd 4.8 Mil

Product Description

The 3M 7000124099 is a blue, film-backed fine line masking tape engineered for precision paint line work on contoured, irregular, and complex surfaces. At 4.8 mil total thickness and 2 inches wide on a 60-yard roll, it lays flat in tight curves and depressed areas without lifting at corners. The thin, smooth backing conforms closely to surface contours, producing clean color separation lines on freshly cured acrylic lacquer, enamel, and polyurethane finishes. Rated for use up to 250 degrees F, it maintains adhesion integrity during elevated-temperature paint cure cycles. Installed by auto body technicians, industrial painters, and finish coaters.

This tape is suited for automotive refinishing, industrial painting operations, and any application requiring a sharp, defined paint edge on non-flat geometry. It performs on body panels, moldings, trim lines, and other surfaces where standard masking tape cannot follow the contour without bridging or lifting. It is designed for interior and controlled-environment use only and should not be used in outdoor or prolonged UV-exposure applications. The roll format allows straightforward dispensing during multi-step finish work.

Key Features

• Film-backed construction at 4.8 mil thickness conforms tightly to curved and irregular surfaces
• Resists lifting at corners and in recessed or depressed surface areas
• Smooth backing tapes cleanly over freshly cured acrylic lacquer, enamel, and polyurethane
• Rated for continuous use up to 250 degrees F — handles elevated paint cure temperatures
• Adhesion to steel: 42 oz per inch width; tensile strength: 10 lbs per inch width
• Elongation at break of 830 percent supports stretch conformance on complex shapes

Compatibility

Designed for use on freshly cured acrylic lacquer, enamel, and polyurethane painted surfaces in automotive refinishing and industrial coating applications. Not intended for outdoor or exterior weathering applications.

Installation Notes

Applied by auto body technicians and industrial painters as part of a masking process prior to paint application. Clean and dry the surface before applying tape to ensure proper adhesion and a clean paint line. Remove tape promptly after paint application and before full cure sets to avoid edge chipping or adhesive transfer. Do not use on outdoor surfaces or expose to prolonged UV or moisture.
