Description
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.

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.

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.

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.

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.

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.

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

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.

Is there a way to remove OB-200 epoxy with a solvent? If so, which solvent should be used (acetone?).
Hi, the OB-200 cannot be removed with a solvent. The epoxy cures hard and can only be chiseled off. Please contact us at temp@omega.com if you need any further assistance.

What is the average thermal conductivity value for the OB-100? I can not find it in the data sheets.
Thank you for your inquiry! There is no listed value for the OB-100 as it is the only OB product that is not designed to be thermally conductive. If improved thermal conductivity is desired the OB-100 should be paired with the OT-201

Can you provide outgassing data for OB-101? Specifically TML and CVCM per ASTM E595? Thank you
Thank you for contacting Omega. We do not have specific information regarding outgassing other than it has the potential of outgassing. Level amount have not been tested and no data to provide.
