Les résines époxydes OMEGABOND™ et silicones OMEGATHERM™ résistent à la chaleur et présentent une bonne conductivité thermique. Elles sont conçues pour réaliser l'adhésion permanente des sondes de température sur une gamme étendue de surfaces –métaux, céramiques, verre, plastiques, papiers et cartons.

OMEGABOND et OMEGATHERM sont livrées sont la forme de 2 composants et conditionnées afin de pouvoir les mélanger et les utiliser facilement. Chacune de ces colles possède les caractéristiques spécifiques nécessaires à des mesures de température précises, rapides et fiables. Elles se caractérisent par une bonne adhérence et une bonne résistance aux efforts, une large plage de température et une conductivité thermique élevée, un fort isolement électrique, une consistance thixotrope, un durcissement rapide et une grande facilité d’utilisation.

Le «Twin Pak» se présente sous la forme d’une pochette plastique transparente divisée en deux compartiments isolés par un séparateur externe. On place la résine dans l’un des compartiments et le durcisseur dans l’autre en quantités égales. Il suffit ensuite de retirer le séparateur pour mélanger les deux composants en malaxant la pochette, puis de couper un coin pour appliquer la colle. Chaque «Twin Pak» est livré avec une notice d’utilisation dans une enveloppe plastique transparente.

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 5 out of 5 by from Omegabond 101 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.

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 3 out of 5 by from Way too long to ship. The product works as expected but a 3 week lead time is ridiculous.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Can you use bond gap beads with this epoxy? If so what beads do you recommend?

Asked by: missioneng
Sorry not sure what bond beads are so please send an inquiry to with additional information so it can be reviewed.

About OB-200 (twin packs). Expiration date: 7/6. Used on 10/23. 1. My catalyst doesn't become a liquid when 65 deg C is applied. Is it because of expiration? Can i fix it? 2. What are the problems if OB-200 is used after its expiration date?

Asked by: Tabull
Thank you for your inquiry. Unfortunately this is expired and therefore will not cure.

What is the expected lifetime of the as-prepared OB-101 when exposed within an environment within the specified limits listed by Omega? Looking to see if this will maintain a bond on the magnitude of decade(s)

Asked by: CC Pressure
Thank you for the inquiry. We do not offer a service life for the cured cements unfortunately. Best regards OMEGA

What is the minimum service temperature for OB-100? The spec sheet states -131F but also states -55C... obviously these two values are not equal. Which is correct? I am currently referencing the spec sheet downloaded today, 2-22-23.

Asked by: Grant
Thank you for your inquiry. The correct minimum temperature is -55°C (-67°F). We will update our manual to reflect this.

Can the 200 cure at room temperature given enough time? Say a few days

Asked by: AxisZ
Thank you for inquiry. Unfortunately OB-200 will never cure at room temperature.

What will happen if the cured OB-200 exposed to the temperature higher than 260 deg C?

Asked by: Tabull
Thank you for your inquiry. The cured OB-200 will start to burn-off.

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?

Asked by: Marco
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

Asked by: AbbCalian
Thank you for your inquiry. The OB-100 can be used for this process.
