KP 97, 98, 99 & KP 12
KERATHERM
®
Thermal Grease
The thermal grease KP 99 is a high-qual-
ity thermal grease. The homogeneous and
thixotropic grease shows a very good fl u-
idity thanks to its good viscosity character-
istics. An optimum surface adaptation
is guaranteed.
KERATHERM
®
Thermal Greases are ceramic-
fi lled single component silicones with a
high thermal conductivity. The non-cross-
linked thermal compounds do not dry out.
The silicone components do not leak from
the compound.
The silicone free thermal compound KP 12
consists of synthetic, thermal polymers
and is suitable for a fast and effective
heat dissipation. The paste is particularly
suitable for silicone sensitive applications.
The KP´s long-term stability guarantees
full operability during the entire life time of
the product. Under normal application con-
ditions, KERATHERM
®
Thermal Grease
does not cure, dry out or melt.
If any separation of the fi ller materials
becomes evident, the KP´s must be mixed
thoroughly before use.
