Does thermal grease still have thermal conductivity after drying? Can it be diluted and continued to use?


Thermal grease is in white or gray state, and it is mainly used in the field of process manufacturing. As long as you buy high-quality products and operate according to the correct construction process, you can ensure excellent thermal conductivity.

What happened to the thermal grease dry?

The thermal grease is in the state of grease before use, and the state remains unchanged when applied to the substrate, and it can be applied without waiting. Thermal grease can only have excellent thermal conductivity when it is in the state of grease. Once it dries out or even cracks, air will enter the position of the crack. Because air is not a thermally conductive material, the thermal conductivity of thermal grease will decrease.

Does thermal grease still have thermal conductivity after drying?

It is a common phenomenon that the thermal grease dries out. It is mainly divided into two types. One is that the surface is slightly dry, which does not affect the use in this case. However, try to buy branded products when buying, such as TENSAN, which focuses on the research of thermal grease, and provides customized thermal grease application solutions, which are widely used and can be used in new energy, military, medical, aviation, ships, electronics , automotive, instrument, power supply, high-speed rail and other industries. The products here are not easy to dry out, and the thermal conductivity remains unchanged for many years.

The other is that cracks appear when the silicone grease dries. In this state, the thermal conductivity of the silicone grease plummets. If the cracks are serious, the thermal conductivity will even be lost. From this we know that it is very important to buy a good quality thermal grease.

Can the thermal grease dry out and continue to be diluted?

The thermal conductive silicone grease dries out, mainly because the oil separation in the silicone grease is more serious, and too much silicone oil is volatilized to dry out. At this time, if you want to debug and continue to use, you need to use silicone oil or methyl silicone oil to dilute it, and at the same time, you must take certain risks.

If the thermal grease dries out, it still has thermal conductivity and does not need to be processed much. If the thermal conductivity decreases or loses thermal conductivity, it can be removed, the original thermal grease can be removed and reapplied. This method is safer.

Although thermal grease is inconspicuous and used in a large amount, it is an indispensable material for electrical appliance manufacturing. As long as the electrical appliance has heat dissipation requirements, it can be used.
