High Temperature and High
Thermally Conductive Paste
OMEGATHERM®thermal conducting paste is a high
temperature and high thermally conductive paste
product. They are specially formulated for permanent
and temporary bonding of thermocouples, thin film
RTDs, thermistors and other temperature sensors,
to most surfaces–metals, ceramics, glass, plastics,
paper products.
OMEGATHERM®products is compounded and
packaged for convenient, easy mixing and application.
Each formulation exhibits important characteristics
necessary for accurate, fast, reliable temperature
measurement. These are: good adhesion and strength,
high temperature rating, high thermal conduction, high
electric insulation, thixotropic consistency, fast cure,
and easy application.
OMEGATHERM®201
OMEGATHERM®201—is a very high thermally
conductive filled silicone paste, ideally suited for many
temperature measurement applications. This thick, grey,
smooth paste wets most surfaces and will not harden on
long exposure to elevated temperatures. It is rated for
continuous use between -40 and 200°C (-40 and 392°F).
OMEGATHERM®201 provides an excellent means of
conducting heat and expanding the heat-path area from
a surface to a temperature measurement sensor, thus
increasing the speed of response and improving
accuracy. Some applications are:
a) Surface Measurement Probes—dab a small amount
on the surface and push the sensor into this area.
b) Temporary bonding and encapsulating of
temperature sensors—simply dab
OMEGATHERM®201 onto the surface or in the
cavity, plant the sensor in the paste, and tape
to hold in place.
This highly versatile paste is supplied in 1⁄2, 2,
16, or 32 ounce size.
