Product Description
TG4000 Thermal Silicone Grease offers excellent thermal properties (4.0 TC and 0.005 TI) and a controlled bond line thickness of 23 micron @35psi, 50oC. Its viscosity and excellent thixotropy make it fit for large–scale production with dispensing, screen printing and stencil printing. It is an excellent, cost effective option for thermally demanding applications with 25um maximum particle size that can support a ~20um BLT.
TG4000 is used for applications with high power density requirements. It is designed to minimize thermal resistance at interfaces, and maintain excellent performance through reliability testing. It provides superior thermal performance with ease of use across a multitude of applications. Its operating temperature range is -40oC to 150oC like the entire Thermal grease product range.

Additional Information
Will I have any issues with fretting(friction) with Greases?
After conducting a thermally degrading test you might realise that these greases are highly filled(~94.5% residual mass). Can this be a cause for concern when it comes to fretting and friction? The short answer is no.
The long answer is that Zinc oxide and aluminum oxide are common fillers in greases and other TIMs. These materials are also used in our phase change TIMs and there has rarely been any issues with fretting (friction) during dispensing or other applications. Fretting is only a concern with boron nitride as filler. Friction related impact is also minimal on low viscosity greases. So you are safe.
