3M™ 2393 is a 7.1 mil crepe paper masking tape with a rubber-based adhesive, engineered for demanding masking applications where heat resistance and clean removal are non-negotiable. Its defining capability is a 325°F heat rating sustained for 30 minutes, making it suitable for bake-cycle environments where standard masking tapes fail.

This tape is widely used in automotive refinishing, industrial coating operations, and manufacturing paint lines where exposure to elevated cure temperatures is routine. The 3-inch width provides broad coverage on flat panels, door frames, and large surface areas, reducing the number of strips needed to mask wide sections cleanly.

The rubber adhesive delivers instant tack and resists lifting and curling during application. The crepe backing conforms to curves and irregular surfaces for clean paint lines with high-solids paints and clear coats. The tape removes hot or cold from most surfaces without damaging the substrate. Each case contains 12 rolls and ships via parcel carrier.
