Supported Applications
The OMEGATHERM® OT-201 Series is a high temperature, thermally conductive silicone grease designed for the permanent and temporary bonding of temperature sensors. It facilitates accurate thermal contact between sensing elements—including thermocouples, thin film RTDs, and thermistors—and various substrate surfaces.
Documented compatible substrates include:
- Metal
- Ceramic
- Glass
- Plastic (PL)
- Paper products (PA)
- Wood (W)
The product is intended for industrial use only and is not designed for human applications.
Operating Conditions & Performance
OMEGATHERM® 201 maintains its properties without hardening during prolonged exposure to elevated temperatures. The continuous temperature range of use is -40°F to +392°F (-40°C to 200°C). Storage at 35°F or below can approximately double the shelf life, which is rated for one year under standard conditions.
Key performance characteristics include:
- Thermal Conductivity: 16 (BTU) (in)/(hr) (ft²) (°F); 0.0055 (cal)/(cm) (sec) (cm²) (°C)
- Volume Resistivity: 10¹⁴ ohm-cm
- Dielectric Strength: 500 volts/mil (19.7 kV/mm)
- Specific Gravity: 2.53 g/cc
- Weight Loss: 0.2% at 100°C for 24 hours
- Consistency: Thick, smooth paste (thixotropic)
- Cure Requirement: Not required
The material is off-white in color. Cleaning requires solvents such as Alcohol, MEK, or Xylene.
Configuration Options
The OT-201 Series is available in four container sizes to accommodate different application volumes:
- OT-201-½: One ½ oz. jar
- OT-201-2: One 2 oz. jar
- OT-201-16: One 16 oz. can
- OT-201-32: One 32 oz. can
The product is compounded and packaged for convenient, easy mixing and application.
Key Product Differences
Variation within the OT-201 Series is defined solely by container size (½ oz., 2 oz., 16 oz., or 32 oz.). The material formulation remains consistent across all sizes, providing identical thermal conductivity, electrical insulation properties, and temperature ratings regardless of package volume.
Important Usage Note: OT-201 is not for use in a vacuum environment as it will outgas. Avoid contact with skin and eyes; wash thoroughly after handling.

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.

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.
