Product Specs
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-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 Temperature
OB-101: Approximately 30 Minutes at Room Temperature
OB-200: Approximately 24 Hours at Room Temperature

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.

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.

OmegaBond 101 is an excellent thermal epoxy
OmegaBond 101 is our go-to thermal epoxy. It bonds well and hard. Excellent when we need to thermocouple a tiny component. Once it is on it stays on.

Continusliy receiveing expired material
Out of the last three orders placed and received, there is always epoxy packs that have expired material sent to us as noted by the expiration date on each pack. This I repeadily happening.

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.

Great Product - Difficult to Apply
We have been using this product for several years to fasten temperature sensors to the back of solar panels. It works great for the application, but it's difficult and extremely messy to apply. Because we are typically working upside down and in cramped spaces, it's extremely difficult to get the product in place without having it drip or get all over your hands. A better applicator for the smaller packages would be really helpful.

Just what I needed
This is a very thick thixotropic material, heat the pouch under a heat lamp for a bit to make it easier to mix and gently squeeze to dispense just where you want it. It must be heated to cure, even 48 hours at room temperature and its still pliable. A few hours at cure temperature its solid and bonds well to metals plastics and FR4.

I'm using OB-200. It really bonds well to any materials. It's also good at high T. But, my new application requires an epoxy having a low thermal conductivty. Do you have a product that has similar properties to OB-200, except for the high thermal conduc
Hi jskim
Please review OB-300. It is designed to be a potting , sealing compound where thermal conductivity is not needed.

Is there a solvent that we can use safely to remove OB-101? thanks
Thank you for your inquiry. There are no solvents to remove this permanent epoxy. Material must be carefully scraped off surface.

What happens to grease if it is use at more than 500F?
The upper rating is 392F for OT-201 and Omega does not recommend using it above that temperature. The characteristics can be altered and the material will no longer perform as specified.

Is Omegabond 101 UL Listed?
Thank you for your inquiry. This product is not UL listed.

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.

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.

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.

Is OMEGABOND 201 Epoxy and OMEGATHERM 201 Silicone Paste safe for use in a vacuum? What about exposure to Oxygen?
The OmegaBond epoxy should be fine in a vacuum as long as it has been properly cured. The silicone paste OmegaTherm 201 however, does not harden and would not be the best choice to be used in a vacuum. Below I have attached a link that might help.
https://br.omega.com/omegaFiles/temperature/pdf/OB-100_OB-200_OT-200.pdf
In terms of its exposure to oxygen there is, unfortunately, no data available that can help me answer that. If you have any more questions please email us at temp@omega.com
