Comparison of the thermal resistance of different pastes
in dependence on the contact pressure
KP92 and KP97 are c eramic-filled single-component silicones 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.
The silicone-free thermal compound KP12 consists of synthetic, thermal polymer and is suitable for a fast and
effective heat dissipation. The paste is particularly suitable for silicone sensitive applications. Its long-term
stability guarantees a full operability during the entire life time of the product. Under normal application
conditions the KP12 silicone-free does not cure, dry out or melt.
