Description

Les ciments OMEGABOND 400 et 300 prennent ou durcissent au contact de l’air par évaporation de leur humidité interne. De ce fait, les conditions atmosphériques peuvent affecter leur mise en oeuvre. Ces ciments à l’air sont le plus souvent appliqués en couches minces successives (épaisseurs inférieures à 6mm) (*).

CRITERES DE SELECTION POUR LES CIMENTS
1. Type d’application – Enrobage, scellement, encapsulation, assemblage, liaison. La couche de ciment nécessaire est-elle mince ou épaisse ? Ceci détermine s’il faut utiliser un ciment à l’air ou au contraire un ciment chimique.
2. Considérations thermiques– Quelle est la température maximale que doit supporter le ciment ? Quelle valeur doit avoir la conductibilité thermique ? Quel doit être le coefficient d’expansion thermique ? Ces paramètres vont déterminer le modèle de ciment approprié.
3. Support – Quels sont les matériaux avec lesquels le ciment sera en contact ?
4. Considérations sur l’application – Durée de vie en pot, temps de prise, méthode d’application, taille de la gâchée, procédure de durcissement.
5. Facteurs divers – Porosité, absorption de l’humidité, résistance électrique, stabilité volumique, jeu/tolérances.

Rated 1 out of 5 by from Doesn't bond to Ready-Made Thermocouples For whatever reason this stuff does not bond to the Ready-Made ThermoCouples. It bonds to metal just fine. Forwarded concerns on this issue. "There are only a few possibilities – The mixture is not correct; the curing time is not sufficient or there has not been enough applied. An outside possibility is the material is no longer viable" ????? "We let it sit over the weekend. It seems to have set up good. There was some left over in the cap we mixed it in and it was hard as a rock. It just isn’t bonding to the wire. There was plenty applied. Material is not viable as in the bonding agent is possibly bad? Sticker on it says use before 3/2018" No response after that...... Had to figure something else out.

Rated 1 out of 5 by from Issues with mixing and curing. Unclear mixing instructions, susceptible to oil even at low temperatures (40°C), and doesn't like to stick to Kapton surface mount thermocouples. You need to apply pressure during the cure and rough up the surface for any hope for it to bond to the Kapton surface mount thermalcouples. I won't be purchasing this 1 part cement again, going with a 2 part for hopefully better results.

Rated 5 out of 5 by from Amazing product! I am using this to attach an aluminum heat sink to an IC on some circuitboards. The thermal conductivity is amazing. It performs just as good as a high quality thermal epoxy, but it's easier to work with. I followed the instructions in the data sheet and it becomes rock hard when fully cured.

Rated 1 out of 5 by from Doesn't work at high temperatures I had bought OB700 and OB400 and they are claimed to be working at high temperatures. Unfortunately, they are a waste at high temperatures (500-600C) and lose strength like anything. As soon as i bring them to room temperature, they offer some strength. Clearly, they are not high-temperature cements. They are just regular ceramic powder grounded.

The inst. for using OB300 specifies three steps for "optimal performance". 1. Dry18-24h RT. Is there benefit of 24 vs 18? 2. What is benefit of 4h 82C? 3. What is benefit of 4h 105C?

Asked by: LouisL
Hi LouisL, Thank you for the inquiry. These are described as additional steps after room temperature curing. And for cases where cement is to be exposed to elevated temperatures above ambient. The additional steps help prevent flaking and chipping. Best regards OMEGA

I am looking at sticking a thermocouple to a kapton heater. Will Omegabond 300, 400 or 500 stick to that material?

Asked by: JoshuaS
Our Omegabond 400 would be best as it has the highest thermal conductivity.

I'm wondering what the thermal conductivity of Omegabond 500 is. I can't find it in the datasheet.

Asked by: jskim
Thank you for your inquiry. The OB-500 has an undefined thermal conductivity.

I want to put smaller rock on the harth of my fire place will this product work for this

Asked by: A henkelman
The material would hold a small object provided it would not be exposed to temperatures above the maximum rating.

I want to seal an end of a stainless steel tubing, with this product additionally the product should withstand when the tube is at 600 degrees Celsius and at 3-4 bars pressure. Will this product be suitable?

Asked by: Ash05
The OB-300 maximum service temperature is 982C so that is fine. We do not put any pressure specifications for a seal so that would have to be tested in the customers application to see if it works.
