3M™ Wire Harness Tape 5074 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 5074 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
Features
• 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
Applications
3M Wire Harness Tape 5074 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 polypropylene parts and similar applications.
