Supersedes 3M Beta Tape 5079 technical data sheet dated June 2004

General Description

3M Wire Harness Tape 5079 is a double-sided acrylic foam sealing tape with excellent initial adhesion, heat resistance and durability compared to conventional butyl sealing tape. Common uses include bonding to rough or highly irregular surfaces, sealing and other applications where a highly conformable tape is required. 3M Wire Harness Tape 5079 has been developed using the technology of 3M Acrylic Foam Tape, which has been used for vehicle interior and exterior part attachment for more than forty years.

3M Wire Harness Tape 5079 offers the following features, advantages and benefits:

•

Demonstrates excellent initial adhesion and static performance against substrates that have uneven surfaces

•

Can be applied to many substrates used for automotive parts, often without special surface treatment

•

Exhibits good workability due to high tape modulus, ease of cutting and wet-out

•

Helps reduce the possibility of staining the bonded surfaces because it is made of a high molecular weight acrylic material

•

Excels in extreme weather, heat and solvent resistance

Alternative Scrim Options

3M Wire Harness Tape 5079 is also available as 3M™ Wire Harness Tape 5079RV, which contains a scrim close to the yellow paper liner.

Applications

3M Wire Harness Tape 5079 is used in the attachment of wire harness assemblies to automobile headliners, attaching interior trim, bonding impact relaxation pads to door panels, bonding of cellular urethane, polystyrene and polypropelene parts and similar applications.

Performance Properties

Performance tests are run using standard test procedures in 3M laboratories. These values presented are typical and not to be used for specification purposes. Peel values depend on test conditions and substrates.

180° Peel Strength

The tape is peeled off at a 180° angle and the adhesion to the substrate is measured with a tensile strength test machine after exposing the tape to the following conditions:
