OMEGABOND™ epoxy and OMEGATHERM™ thermal conducting paste are easy to use epoxies and silicone products. They are specially formulated for permanent bonding of thermocouples, thin film RTDs, thermistors and other temperature sensors, to most surfaces–metals, ceramics, glass, plastics, paper products. OMEGABOND™ and OMEGATHERM™ products are 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.
OB-100 is available in 1/4 oz or 1 oz Twin Packs and 1 lb as 2 cans, 1 of resin and 1 of hardener.OB-101 is available in 1/2 oz or 2 oz Twin Packs and 1 lb as 2 cans, 1 of resin and 1 of hardener.
OB-102 is available in kits for 16oz resin/1 oz catalyst, 2oz resin/1/2 oz catalyst, and 1/2oz resin/1/2 oz catalyst.
OB-200 is available in a 2 oz Twin Packs or 1 lb as 2 cans, 1 of resin and 1 of hardener.
OT-201 is available in 1/2 oz or 2 oz Twin Packs or in cans as 1 lb or 2 lb (two 1 lb cans).
“Twin pak” packaging is supplied to ensure the user with accurate proportioning of resin and catalyst, as well as to provide a clean, fast means of mixing. The “Twin Pak” is a flexible, transparent plastic pouch, separated into two isolated compartments by means of a removable external divider. In one compartment is the resin, the other the pre-measured catalyst. To use, remove the divider, mix the two components by kneading the pouch, then snip off a corner to dispense. Each “Twin Pak” comes with an instruction sheet, enclosed in a clear, heat-sealed plastic envelope.
Please note that once mixed, the OB-100, OB-101 and OB-200 epoxies have the following "Working Times" (also referred to as "Pot Life"):
OB-100: Less Than 8 Minutes at Room TemperatureOB-101: Approximately 30 Minutes at Room Temperature
OB-102: Approximately 45 minutes at Room Temperature
OB-200: Approximately 24 Hours at Room Temperature
Specifications are subject to change without notice. Suitability of this product for its intended use and any associated risks must be determined by the end customer/buyer in its final application.

Formula changed!
We use this epoxy weekly and have been buying it for many years. However, the last batch we purchased was a gel formula instead of the liquid we have become accustom to. Do no like it very much as it is difficult to fill a syringe and use it in the field.

I have been using OB-101 in the small packs for several years now to bond the printed circuit board to the frame/case, which as also the heat sink, on automotive Engine Control Modules manufactured with surface mount components. It withstands thermal expansion and contraction, and vibration, while also being a good thermal conductor and yet a good electrical insulator.
Shelf life is substantially longer that what is marked on the packets.

Good Product and great service.
We have been using this epoxy for many years and have not experienced any issues with the exception of the more recent texture difference with part A. It used to be smooth and now it is more chunky and dry, making it hard to measure. By warming it up beyond room temperature, we are able to soften it making it easier to portion. This extra step takes away 1 star. The service the company provided is excellent with order follow through and general customer service.

Thermal Epoxy Works Great
I like the variety of potting and full cure times at room temp and with heat. This tends to hold on to my thermocouples well.

Way too long to ship.
The product works as expected but a 3 week lead time is ridiculous.

Used on automotive ECM's.
I have used this for several years on automotive ECM's where SMD power transistors and switches are soldered to the PCB, which is then attached to an aluminum case for heat dissipation. This a requires a product with good thermal conductivity with a high dielectric rating. It has a very smooth and easy to spread consistency, and a good balance of pot life v.s. cure time.

Hi, I am using OB-102, I received A and B parts but i could not find the proportion of mix. Please let me know the proportion both by weight and by volume. Thank you
Thank you for your inquiry. For OB-102, the mix ratio is 100 parts material to 3.5 parts catalyst by weight.

Can you recommend a filler / thickener for OB-200? I am looking to bond a stainless cooling tube to a stainless plate and the OB-200 is a bit too thin to get a nice fillet. Would Stainless steel powder be an acceptable filler for OB-200?
Hi,
Omega does not sell nor have we tested any thickening agents with the OB-200. If you need a cement with a bit thicker consistency you might want to look at a cement like the OB-600 as a possible substitute.

Hi, we are looking for a tap or epoxy to secure thermocouples on PCB surface that can start from -20C to +100C for thermal cycling test, the tap or epoxy is to help keep the thermocouples on the surface of the PCB during a slight shock or vibration
Thank you for your inquiry. The OB-100 can be used for this process.

Is OMEGABOND 101 Two Part Epoxy good for potting electronics? How well does it handle thick layers and or voids between adhered surfaces? How thick/viscus is the epoxy as you work with it?
OMEGABOND®100—a fast (8 to 12 minute setting time), room temperature, two-part epoxy. Recommended for easy temporary and permanent bonding of beaded wire and “cement-on” thermocouples. Adheres to metals, ceramics, epoxy laminates, glass, wood, concrete and many other materials—for temperature measurements up to 129°C (265°F). It is not recommended for those endeavoring to achieve the ultimate in precision and speed of response, since this unfilled system has a relatively low thermal conductivity.Temporary installation of beaded wire thermocouples can be achieved by using a very small amount of OMEGABOND® 100 to tack the bead to the surface and packing OMEGATHERM® 201 around the exposed surface to improve heat transfer. This clear syrup consistency—100% solid adhesive — contains no solvents and has good strength and electrical insulation characteristics. Note: The working time after mixing the 2-part system at room temperature is only 6 to 8 minutes. OMEGABOND 100 is available in “Twin Pak” packs and 1- and 2-pound kits.
For larger gaps, up to 1/4", review the OB-400 High Temperature Air Set Cement.

What is the shelf life and optimal storage conditions for OB-101-1/2 packs? The standard 101 manual says 70F and one-year shelf life if container remains sealed. Just looking for clarity for the art packs.
The environmental storage and shelf life is the same regardless of the amount being stored.

Can you use bond gap beads with this epoxy? If so what beads do you recommend?
Sorry not sure what bond beads are so please send an inquiry to temp@omega.com with additional information so it can be reviewed.

What is the MINIMUM continuous temperature rating for cured OB-101?
Hi Matt,
Thank you for the inquiry. Minimum temperature -55 deg C.

Can any of the omega bond thermal epoxies cure at room temperature?
Thank you for your inquiry Apz24. The OB-100 and OB-101 cure at room temperature. The OB-100 has a cure time of 8 to 12 minutes set at room temperature. The OB-200 has to cure at elevated temperatures. The OT-201 does not have a required cure time.
