3M MMM2321 Masking Tape 1 Inch X 60 Yards Paint Applications

Product Description

The 3M MMM2321 is a general-purpose crepe paper masking tape designed for paint masking, bundling, holding, and surface protection across a range of trade and light industrial applications. It features a thick crepe paper backing with a rubber-based adhesive and a solvent-resistant saturant that helps maintain tape integrity during medium-temperature paint bake operations. Each roll measures 1 inch wide by 60 yards long and weighs approximately 0.46 pounds. The rubber adhesive bonds instantly to surfaces and releases cleanly in one piece without leaving residue, making it a reliable choice for painters, contractors, and maintenance technicians who need consistent results on difficult surfaces.

This tape is suited for both residential and light commercial paint work where sharp, clean paint lines are required. The thick crepe backing resists paint bleed-through from latex and oil-based paints and holds up during medium-temperature bake cycles, making it appropriate for automotive refinishing environments as well as general construction and maintenance painting. It also performs in non-paint applications such as bundling materials, temporarily protecting surfaces, and securing components during assembly or transit. The easy-tear feature allows for quick, tool-free application on the job site.

Key Features

• Thick crepe paper backing resists paint bleed-through from latex and oil-based paints
• Rubber adhesive provides instant adhesion and clean one-piece removal without residue
• Solvent-resistant saturant supports durability in medium-temperature bake operations
• Easy hand-tear design speeds application without scissors or a knife
• Sliver-resistant construction reduces tape fragmentation during removal
• Suitable for paint masking, bundling, holding, and surface protection on difficult surfaces

Compatibility

Designed as an OEM-style general-purpose masking tape compatible with standard tape dispensers accepting 1-inch core rolls. Performs with latex and oil-based paint systems in standard and medium-temperature bake environments.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material for best adhesion and clean removal. Remove tape promptly after the paint operation is complete to prevent adhesive transfer or surface damage, particularly on freshly painted or sensitive substrates. No special tools are required for application; standard tape dispensers or hand application are appropriate. Follow all applicable safety data sheet guidance when working with paints and solvents in the same work area.
