Thermal Silicone Grease Nitecore SG07 tube 5 g – thermal interface paste for LEDs, flashlights, electronics

Nitecore SG07 is a silicone-based thermal grease supplied in a 5 g controlled-application tube designed to improve heat transfer between electronic components and heat sinks. Formulated for use with LEDs, flashlights and compact electronics, this thermal interface paste fills microscopic surface irregularities to reduce thermal resistance and help maintain lower operating temperatures and stable performance.

Advantages

The silicone formulation provides stable viscosity for easy application from a small tube, enabling precise placement on LEDs, transistor packages and metal-to-metal interfaces. Nitecore SG07 is electrically non-conductive and resists drying and cracking over typical operating temperature ranges, offering consistent thermal contact over time. The paste reduces hot spots by improving contact between mating surfaces and can contribute to longer component life and more reliable operation.

Suitable for

• High-power LEDs and lamp modules
• Handheld flashlights and torch assemblies
• Small electronic PCBs and power semiconductors
• Heat sinks, metal mounting plates and thermal pads replacement

Key specifications

• Form: silicone-based thermal grease (paste)
• Net weight: 5 g tube for controlled application
• Electrical properties: electrically non-conductive
• Application temperature range: suitable for typical LED and small-electronics operating temperatures
• Viscosity: medium, formulated for precise dispensing from a small tube

How to use

Ensure both mating surfaces are clean, dry and free of old thermal compound, grease or debris. Apply a small, even amount of SG07 to the warmer component surface; a thin, continuous layer is sufficient to fill microscopic gaps without excessive squeeze-out. Reassemble the parts and tighten mounting hardware to achieve firm contact. If necessary, remove excess paste around the edges with a lint-free cloth or swab and isopropyl alcohol. For replacement or maintenance, clean surfaces thoroughly before reapplying fresh thermal grease.

Recommendations

Use minimal amounts to achieve full coverage—excess paste does not improve thermal transfer and may increase mess. Avoid applying to exposed electrical contacts. Store the tube capped in a cool, dry place to prevent contamination or drying between uses.
