OT-201

OMEGATHERM®Thermally Conductive Silicone Paste

INSTRUCTION

SHEET

M0066/1104

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.

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

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.

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.

FOR INDUSTRIAL USE ONLY.
