Introduction
OMEGATHERM® 201 is a thermally conductive, “Heat Sink” silicone grease. It has a very high thermal conductivity coupled with high insulation resistance and high dielectric strength. The term heat sink compound or thermal joint compound is used to describe this type of material. It does not harden on long exposure to elevated temperatures, but retains its past-like consistency. It is rated for continuous use between -40°F and +392°F (40°C and 200°C).
OMEGATHERM® is available in four quantity sizes, from a 1⁄2 oz. jar to a 2 lb. can, as outlined below.
well with insulated wire thermocouples. Simply dab this paste on the surface or into a cavity, put the sensor in the paste, and tape to hold.
C.Thermocouple Wells (to 200°C)-improve the response time of your thermowell assemblies. Simply put enough OMEGATHERM 201 into the bottom of the wells to cover the active length of the sensor. This application holds for vertical wells or those canted down.
D.NOT FOR USE IN A VACUUM. OT-201 will outgas if used in a vacuum.

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.
OMEGATHERM 201 improves the heat transfer between a solid state relay and its finned heat dissipating heat sink. Apply a thin layer of “201” thermal compound to the bottom of the solid state relay (SSR), then securely mount the SSR on the finned heat sink with the supplied screws.
Instructions for Use
Although OMEGATHERM 201 does not normally settle in its container, storage for long periods of time at elevated temperature may result in a slight separation of the conductive fillers from the silicone oil. If this condition is seen to exist, the fillers may be easily mixed by hand or mechanical mixing.
OMEGATHERM 201 may be dispensed through a nozzle using any appropriate hand operated or automatic equipment. For some applications, it will be convenient to apply thin films with a stiff brush.
To CLEAN OT-201 from surfaces, use a solvent containing Alcohol, MEK, or Xylene. Repeated use is required to completely clean silicon grease from surface.
Applications
A.Surface Measurement Probes-dab a small amount on the surface and push the thermocouple into this area.
B.Temporary Temperature Monitoring of Surfaces and Bodies-For applications to 392°F (200°C). OT-201 works
Hygiene
MAY CAUSE IRRITATION.
1.Avoid contact with skin and eyes.
2.Wash thoroughly after handling.
First Aid
1.In case of contact, wash skin thoroughly with soap and water.
2.For eyes, flush with water for 15 minutes and consult physician immediately.
