Description

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

Rated 4 out of 5 by from 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.

Rated 3 out of 5 by from 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.

Rated 5 out of 5 by from Great product! Fast shipment! Great product! Fast shipment! Easy to use. I knew this product from other Engineer. I'd recommend this product to other Engineers too.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Great for thermal testing of equipment Used to test the thermal conductivity internally in electronics. Works like a charm. Very easy to mix up on a paper plate with a spoon and then I just dip my cable tips in the mixture and then apply to the equipment. Very simple. Does have an odor but stay a well ventilated room during mixing. I even wear gloves from the local auto parts store that are disposable.

Rated 3 out of 5 by from Hold up to thermal cycling well! But..... I was looking for an amount to epoxy on 10-20 thermocouples but found this hard to proportion into seperate portions. Also the website refers to setting time to be a lot less than the paperwork says that came with the product. Overall I was able to still use the product and it has performed well

Rated 1 out of 5 by from Failed spectacularly Tried to use this to bond copper to ceramic. Worked for 2 days, then failed spectacularly at temperatures of 240 degrees C. The part failure ended up costing us days of lost time fixing the machine. Might have been due to mismatched thermal expansion coefficients causing stress in the adhesive. So either the epoxy failed due to stress, or due to temperature. Probably temperature. Who knows. I guess the lesson is: don't use epoxy at elevated temperatures. Just because it says it can do it, doesn't mean it can.
