3M 7000123903 Masking Tape 7.9 Mil 12 Mm 60 Yd

Product Description

The 3M 7000123903 is a paper-backed masking tape designed for paint masking applications in automotive, industrial, and general trade work. It measures 12 mm wide and 60 yards long with a 7.9 mil total thickness. The rubber adhesive delivers a tensile strength of 29 lb/in, holding edges cleanly during spray or brush application. The tape conforms to irregular surfaces, resists paint bleed-through, and releases without adhesive transfer or paint flaking. It meets ASTM D-6123 standards and is rated for bake-cycle use, making it suitable for automotive refinish shops and industrial coating lines where elevated heat is part of the process.

This tape is used in paint masking on automotive panels, metal fabrication, and general industrial finishing where a clean paint line and residue-free removal are required. It performs in bake oven environments up to 325 degrees F (163 degrees C) for up to 30 minutes, which covers most standard automotive refinish bake cycles. HVAC sheet metal shops, electricians marking surfaces, and plumbing contractors also use general masking tape of this type for surface protection and temporary identification during rough-in work.

Key Features

• Rubber adhesive with 29 lb/in tensile strength holds under spray and brush application
• Rated for bake temperatures up to 325 degrees F (163 degrees C) for 30 minutes
• Adhesive transfer-resistant and paint flake-resistant for clean removal
• Conformable paper backing follows curves and irregular surfaces
• Meets ASTM D-6123 standard for pressure-sensitive tape
• Not rated for outdoor or prolonged UV exposure

Compatibility

Designed as an OEM-style general-purpose masking tape for paint masking in automotive refinish, industrial coating, and general trade applications where a rubber-adhesive paper tape rated to bake temperatures is required.

Installation Notes

Apply to clean, dry surfaces free of dust, oil, and loose material for best adhesion and clean removal. Remove the tape promptly after the bake cycle or paint flash period is complete — extended dwell time beyond recommended conditions increases the risk of adhesive residue. Do not expose to outdoor environments or prolonged sunlight. This tape is a consumable applied by hand; no special tools or trade licensing are required, though use in automotive refinish environments should follow applicable shop safety and VOC regulations.
