3M General Purpose Masking Tape 234 is a 5.9 mil crepe paper tape with a rubber adhesive and a saturant-treated backing engineered to resist heat, moisture, and solvents. The treated backing maintains tape integrity during medium-temperature bake cycles, holding up to 250°F for 30 minutes without flagging or adhesive bleed.

Designed for spray painting, powder coating prep, and general industrial masking, this tape delivers sharp paint line definition and conforms to irregular contours. It bonds reliably to powder-coated and stainless steel surfaces, making it a practical choice for automotive finishing, metal fabrication, and production assembly workflows.

Each roll is 1/2 inch wide by 60 yards long, and cases contain 72 rolls weighing approximately 15.46 lbs. Ordering by the case reduces per-roll cost for operations with consistent masking volume.
