Keratherm Thermal Grease

Ceramic-filled single-component silicone with 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 KP 96/97/98 is not required, therefore they can be stored in normal climates for up to 12 months.

If any separation of the filler materials becomes evident, KP 96/97/98 must be mixed thoroughly before use.
