3M 7000049218 Adhesive Transfer Tape 0.75 in 180 Yd

Product Description

The 3M 7000049218 is an adhesive transfer tape built on 3M High Performance Acrylic Adhesive 350, delivered on a white 78 lb. extensible kraft paper liner. At 5.0 mils thick, this tape delivers strong adhesion to both high and low surface energy substrates, including powder coated paints and plastics. The adhesive is fiber reinforced for roll stability in narrow widths and resists oozing during processing. It is designed for use in automated dispensing equipment and hand-applied bonding operations. Licensed HVAC, plumbing, electrical, and general trade installers use this tape where a clean, liner-based transfer bond is required without a carrier film.

This transfer tape is suited for bonding dissimilar materials and substrates with rougher surface profiles. The 0.75 inch width and 180 yard roll length make it practical for both high-volume automated line applications and bench assembly work. It performs across a broad temperature range, rated for short-term exposure up to 450 degrees F and continuous long-term service up to 300 degrees F, making it appropriate for applications near heat-generating equipment or in warm enclosures.

Key Features

• 5.0 mil adhesive thickness for high bond strength to low surface energy substrates and powder coated paints
• 78 lb. extensible kraft paper liner adds tensile strength for narrow-width automated dispensing
• Fiber-reinforced adhesive resists oozing and maintains roll stability in narrow widths
• Short-term temperature resistance to 450 degrees F and long-term resistance to 300 degrees F
• Excellent chemical resistance with strong shear and peel performance at elevated temperatures
• Low odor formulation suitable for enclosed or occupied work environments

Compatibility

Designed for bonding high and low surface energy materials, including powder coated paints, plastics, and surfaces with moderate roughness, in both automated dispensing and manual assembly applications.

Installation Notes

Surface preparation is critical before application — clean surfaces of oils, dust, and loose particles for maximum adhesion. Apply firm, even pressure across the bond area after positioning. When used near electrical enclosures or heat sources, verify that the operating temperature range of the assembly does not exceed the tape's rated limits. No special tools are required for hand application; automated dispensing equipment should be configured for the 0.75 inch roll width.
