3M Specialty High Temperature Masking Tape 501+ is a 7.3 mil purple crepe paper tape with a rubber-based adhesive, rated to withstand 300°F for up to 30 minutes without flagging, lifting, or adhesive transfer. The purple color provides immediate visual identification on the production floor, simplifying masking and unmasking steps during quality control.

This tape is built for industrial paint and coating operations where heat exposure is unavoidable. Automotive refinishing, aerospace component painting, powder coating lines, and general manufacturing environments rely on it to hold sharp, clean lines through oven cycles and elevated-temperature curing processes. The easy-unwind construction reduces hand fatigue during high-volume, sustained application.

The crepe paper backing conforms readily to curves, contours, and irregular surfaces, eliminating the need to pre-cut or notch tape on complex geometries. Each case contains 24 rolls measuring 1-1/2 inches wide by 60 yards. The product ships via parcel carrier.
