3M 7010333945 Thermally Conductive Adhesive Transfer Tape

Product Description

The 3M 7010333945 is a pressure-sensitive thermally conductive adhesive transfer tape designed to create a reliable heat-transfer path between heat-generating components and cooling devices such as heat sinks, fans, heat spreaders, and heat pipes. Loaded with thermally conductive ceramic fillers, it bonds without a heat cure cycle — pressure alone is sufficient to form a strong bond and effective thermal interface. The adhesive is modestly soft, allowing it to conform to non-flat surfaces, wet effectively to a wide range of substrates, and deliver both high adhesion and good electrical insulation properties. This tape is used by electronics assembly technicians, thermal management engineers, and HVAC or industrial equipment service professionals.

This tape is suited for applications where reliable thermal conductivity and electrical insulation are both required at the bond line. Typical use cases include bonding heat-generating electronic components to heat sinks, heat spreaders, or heat pipes in residential and commercial HVAC systems, power electronics, LED assemblies, and industrial equipment. The roll format — 4 inches wide by 36 yards long — makes it practical for high-volume or repetitive production and service work.

Key Features

• Pressure-sensitive bond — no heat cure cycle required
• Thermally conductive ceramic fillers provide a preferential heat-transfer path
• Soft, conformable adhesive wets well to non-flat and irregular substrate surfaces
• Provides both thermal conductivity and electrical insulation at the interface
• Excellent adhesive performance with good wetting and flow onto diverse substrates
• Roll format supports efficient application in production and field service environments

Compatibility

Designed as a thermally conductive interface material for bonding heat-generating components to heat sinks, heat spreaders, fans, and heat pipes across a broad range of substrates commonly found in HVAC, electronics, and industrial equipment applications.

Installation Notes

Application is performed by trained assembly or field service technicians. Surface preparation is critical — clean and dry both mating surfaces before applying the tape to ensure full adhesion and thermal contact. Apply firm, uniform pressure across the bond area to activate the pressure-sensitive adhesive. No heat cure or additional fasteners are required to complete the bond, but ensure the assembly is fully powered down before working on any heat-generating electronic components.
