Keratherm - Thermal Grease
KP 68, KP 77, KP 92, KP 93
Applications:
Notebooks
Desktop CP’U´s
IGBT units
Ceramic-filled single-component silicone with a high thermal conductivity. The non-crosslinked thermal compounds do not
dry out. The silicone components do not leak out of the compound. Special storage of Keratherm “Thermal Grease” is not
required, therefore they can be stored under normal climate conditions for up to 12 months. If any separation of the filler
materials becomes evident, the KP´s must be mixed thoroughly before use.
