Thermal Grease

LOCTITE TG 100 is recommended for high temperature heat transfer in normal applications. It is used between heat generating devices and the surfaces to which they are mounted or other heat dissipating surfaces.
Thermal Conductivity - 3.4 W/(m-K)

LOCTITE TCP 8010 thermal grease is recommended for use in assembly of parts requiring high temperature heat transfer. It is used between heat generating devices and the surfaces to which they are mounted or other heat dissipating surfaces.
Thermal Conductivity - 1.0 W/(m-K)
