Composed of carbon micro-particles which lead to an extremely high thermal conductivity. It guarantees that heat generated from the CPU or GPU is dissipated efficiently. The Heat Sink Paste is metal-free and non-electrical conductive which eliminates any risks of causing short circuit, adding more protection to the CPU and VGA cards. With an ideal consistency, is very easy to use, even for beginners. Once applied, you do not need to apply it again as it will last at least for years. Generally used as a thermal coupling of electrical / electronic devices to heat sinks such as base or mounting studs of transistors, diodes and rectifiers It is used for maintaining a positive heat-sink seal that improves heat transfer from the electrical / electronic component / device to the heat sink or chassis, thereby increasing the overall efficiency of the component / device
