PRODUCT DESCRIPTION:
Thermal-Grease 4 Heat Sink, Thermally Conductive Compound, MIL-DTL-4-7113, Low Bleed, Low VOC is an opaque white heat sink grease compound, which is applied to the base and mounting studs of transistor and diodes to provide a positive heat sink seal, this facilitates heat transfer away from electrical/electronic components and into heat sinks, thereby increasing the overall efficiency and performance of the device.
Thermal-Grease 4 Heat Sink, Thermally Conductive Compound, MIL-DTL-4-7113, Low Bleed, Low VOC is silicone material, heavily filled with efficient heat conductive zinc oxide and a binding agent, this combination promotes high thermal conductivity, high temperature stability, and the lowest amount of bleed and evaporation.
Thermal-Grease 4 Heat Sink, Thermally Conductive Compound, MIL-DTL-4-7113, Low Bleed, Low VOC thermal compound resists changes in consistency temperatures up to 180C; function as heat transfer media, durable dielectric insulation, barrier against environmental contaminants and as a stress-relieving shock and vibration absorber over a wide temperature and humidity range.
Thermal-Grease 4 Heat Sink, Thermally Conductive Compound, MIL-DTL-4-7113, Low Bleed, Low VOC thermal paste is resistant to ozone and ultraviolet degradation and has good chemical and solvent stability, good interference between the heat producing device and the heat transfer media, and low surface tension that enables them to wet most surfaces. Thermal-Grease 4 Heat Sink, Thermally Conductive Compound, MIL-DTL-4-7113, Low Bleed, Low VOC will not harden, dry, or melt after 1200 hours @ 205C.
