L'aperçu du produit
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 101I 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 GreatI 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
Asked by: Muhammad
Thank you for your inquiry. For OB-102, the mix ratio is 100 parts material to 3.5 parts catalyst by weight.

What is the minimum temperature for this adhesive? I am looking for an adhesive to attach heaters to a surface that could experience temperatures down to -200C. Would the adhesive still work at these very cold temperatures?
Asked by: SM2022
Thank you for your inquiry SM2022. The minimum temperature rating for OB-101 is -55 deg C and for OB-200 it is -20 deg C. We do not have much information but it may just shatter at -200 C. For more information, please email temp@omega.com

Is there a solvent that we can use safely to remove OB-101?
thanks
Asked by: Simon12345
Thank you for your inquiry. There are no solvents to remove this permanent epoxy. Material must be carefully scraped off surface.

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.

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?
Asked by: spacer
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.
Asked by: BillD
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?
Asked by: missioneng
Sorry not sure what bond beads are so please send an inquiry to temp@omega.com with additional information so it can be reviewed.
