What is the thermal conductivity of the paste? In the table, you have specified Thermal conductivity 16 kBTU in/(hr ft 2 °F). In the manual pdf, the Thermal conductivity specified there is 16 BTU in/(hr ft 2 °F). Which one is right?

The correct Thermal Conductivity value is 16 BTU in/(HR ft 2 F) for the OT-201.

Is this paste available in a smaller box? The 16oz seems to be too much for my application and a lot of it would be wasted. The website says that the paste is available in 1/2 and 2 oz jars. But I did not find a option to select it

Thank you for your inquiry ad09. Unfortunately, the smaller quantities of the OB-201 have been discontinued. The only size we currently offer is the 16 oz.

can you provide viscocity numbers so we can determine if pneumatic syringe application is an option.

Thank you for your inquiry. Unforunately we have no viscosity information for this product.

I see that our container has an expiration date. Can you clarify what properties of the paste change or lessen after the expiration date? (in other words, does it get stiffer, get less conductive, etc?)

Thank you for your inquiry. If material is properly stored, there should be no loss of performance or properties past the expiration date. We do not have any test data to determine if there will be any physical changes, except maybe the material can dry out. Prior to the expiration date the OT-201-1/2 will meet all the published specifications.

What is the cleanup process when applied on metallic and/or ceramic substrates? Thanks in advance.

Solvents for clean up are; Alcohol or MEK or Xylene

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- and 2-ounce jars, as well as in one- and two-pound containers.

Rated 4 out of 5 by MrBillSK from Very Good Thermal Conductivity. The product was easy to apply (Not quite as thick as typical peanut butter - never tried it on bread though). I was hoping it would be thicker and provide some mechanical strength to hold the thermocouple in place, but that's not quite the case. I ended up using polyimide high temperature tape to hold the thermocouple in place. A dab larger than, say, a 1/8" sphere, might drip if on the gravity side of a surface parallel to the earth (Upside down) It seemed to work well to get the temperature of the material I was measuring to saturate the thermocouple device. The product is good, but I may look for something similar to epoxy if I can remove it easier than epoxy.

Rated 5 out of 5 by Rocketman55 from Great Product I used this on a mini Molder and Extruder and it is all it says it is. The temperature response on the J type sensors was more steady on units.

Questions et réponses

Does this material ever cure or does it stay wet forever?

Asked by: Anonymous

Thank you for your inquiry. Yes, the OT-201 does cure.

I'm searching for a paste that can withstand 300~400 degree celsius with good thermal conductivity and compatible with high vacuum condition(~10^-5 torr) to bond the sample in a vacuum annealing furnace, is any of your product meet the requirements?

Asked by: Hank

Thank you for connecting with Omega, unfortunately we do not have a product that meets your requirement. Our OT-201 series paste will only go to 200 deg C.
