401+ Green Masking Tape

3M 401+ is a green crepe-paper masking tape with a rubber adhesive. It comes in a continuous roll measuring 48 mm wide and 55 m long. The tape suits painters, automotive refinishers and general tradespeople who need clean paint lines on metal, glass or trimmed surfaces.

7.30 mil thickness and 250 °F limit

At 7.30 mil thick the tape resists bleed-through on typical solvent-based and water-based coatings. It holds up to a maximum performance temperature of 250 °F, so it survives low-bake cycles. Tensile strength of 26 lb/in and 10 % elongation mean it tears cleanly by hand but will snap if stretched aggressively around tight radii.

Rubber adhesive and ASTM standards

The rubber adhesive delivers 36 oz/in adhesion that grips instantly yet releases cleanly within the manufacturer's unspecified removal window. Conformance to ASTM D-3330, D-3759, D-3652 and D-6123 confirms consistent peel, tensile and thickness quality across rolls. Not rated for extended outdoor UV exposure or temperatures below 70 °F.

Questions about this item

Will the 48 mm wide roll mask cleanly next to my existing 36 mm tape lines?

The 48 mm width covers a broader edge than 36 mm tape, so overlapping seams stay sealed; both use rubber adhesive on crepe paper for consistent tack.

How do I confirm the 7.30 mil thickness is performing at the 250 °F upper limit?

After bake cycles, check that the green backing removes cleanly within the 10 % elongation spec and shows no adhesive transfer per ASTM D-3330 and D-3759.

Does the 55 m roll include a dispenser or must I buy one separately?

The box contains only the continuous 55 m roll of 401+ green masking tape; a dispenser is not included and must be sourced separately.
