**GENUINE** DOW CORNING® 340 (DC340) HEAT SINK COMPOUND. A grease-like silicone material, heavily filled with heat conductive metal oxides. This combination promotes high thermal conductivity, low bleedand high-temperature stability. The compound resists changes in consistency at temperatures up to approximately 350ºF (177ºC). In doing so, it helps maintain a positive heat sink seal to improve heat transfer from the electrical/electronic device to the heat sink or chassis, thereby increasing overall efficiency of the device. White color.
USE ONLY THE GUARANTEED BEST
DOW CORNING products are recommended by top manufactureres around the world.
FEATURES:
- Highly filled w/ metal oxides for high thermal conductivity
- Low bleed
- Stable at high temperatures
- Non-curing, does NOT need curing and does NOT harden
- Hydrophobic/Water Resistant
- Non-sag, nonflowable, stays in place
APPLICATIONS:
Dow Corning® 340 Heat Sink Compound is applied to the base and mounting studs of transistors, diodes and silicon-controlled rectifiers. It can also serve as an effective thermal coupler for many heat sink devices where efficient cooling is required. It is also suitable for aircraft engines where heat sink properties are required. This product has also been used as a high-voltage corona suppressant, nonflammable coating in connections for flyback transformers and TV sets and similar applications.
A proven and economical thermally conductive solution for low power applications. This grease can be used in a wide array of industrial applications including power components/power supply for Audio; Video (DVDs, TV Sets, etc.); broadcasting equipment; car-audio, frequency drivers (or frequency inverters) on automation equipment and some minor applications on temperature sensor for auto.
Can be used as a thin interface or encapsulant. For interface, apply grease with a squeegee through a stencil or screen to print a grease pad or spread out bulk material with a spatula.
BEWARE OF LOWER PERFORMANCE PRODUCTS AT A LOWER PRICE!
- 100% silicone grease does get in between all the voids like DOW 340 does but plain silicone grease does not have metal oxide additives which considerably improve thermal conductivity between surfaces. DOW 340 has more than 60% metal oxide content to promote high thermal conductivity.
- Some heat sink compounds have similar thermal conductivity coefficients to DOW 340 but they have short term temperature exposure limits of as low as 50ºC (122ºF) which is about the normal operating temperature of many PC CPU and other computer chips and electronic components. DOW 340 resists changes in consistency at temperatures up to approximately 350ºF (177ºC) and has a maximum operating temperature of 392ºF (200ºC).
