3M 7010333946 Thermally Conductive Adhesive Transfer Tape

Product Description

The 3M 7010333946 is a pressure-sensitive adhesive transfer tape loaded with thermally conductive ceramic fillers, 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. No heat cure cycle is required — bond formation relies on pressure alone, making field application straightforward. The tape is modestly soft and conforms well to non-flat substrates, delivering high adhesion and strong thermal interface performance. It also provides good electrical insulation properties alongside its thermal conductivity. This tape is supplied in a roll measuring 4 inches wide by 36 yards long.

This tape is suited for electronics assembly, thermal management applications, and industrial environments where a thin, conformable interface material is needed between a heat source and a cooling device. It is commonly installed by electronics technicians, field service engineers, and skilled tradespeople working on control boards, power supplies, LED assemblies, and similar heat-generating components. Its ability to wet onto a wide range of substrate surfaces makes it adaptable across many bonding scenarios without special surface preparation or curing equipment.

Key Features

• Pressure-sensitive bond — no heat cure cycle required for adhesion or thermal interface formation
• Thermally conductive ceramic fillers provide a preferential heat-transfer path
• Conforms to non-flat and irregular substrate surfaces for consistent contact
• Provides both thermal conductivity and electrical insulation in a single layer
• Good wetting and flow onto a wide range of substrate materials
• Roll format — 4 inches wide by 36 yards for flexible cut-to-size application

Compatibility

Designed as an interface material between heat-generating components and heat sinks or other cooling devices across a broad range of electronic and industrial assemblies. No specific system or model compatibility data was provided for this SKU.

Installation Notes

Power down and de-energize any assembly before applying this tape to heat-generating components. Clean and dry both mating surfaces before application to ensure maximum adhesion and thermal contact. Apply firm, uniform pressure across the tape surface after placement to fully activate the pressure-sensitive bond. Cut to size using clean shears or a straightedge to maintain edge integrity on the roll.
