Product Specs

Chemical Set Cements set or cure by an internal chemical action which does not require exposure to air. Chemical Set Cements can be used in thick applications (applied in thicknesses greater than 1/4")*.

1. Type of Application –Potting, sealing, encapsulating, assembling, bonding. Is a thick or thin film of cement required? This dictates whether or not an air set or a chemical set cement can be used.
2. Thermal Considerations –What is the maximum temperature that the cement must withstand? What degree of thermal conductivity is needed? What degree of thermal expansion is allowed? These properties are then matched to the appropriate cement.
3. Solvent – 10% Sodium Hydroxide. However it’s difficult to remove cured cement.
4. Substrate – What materials will the cement be in contact with?

Rated 4 out of 5 by from Good but has limitations you have to consider Works well, good adhesion. The grain size is fairly large so it can’t get into very fine gaps. This cement destroys glass fiber insulation on thermocouple wires which I found out only by wrecking several new thermocouples. I wish Omega would have indicated that before I wasted the time and money.

Rated 4 out of 5 by from Good properties I bought this for thermalcouple application and works good. Just be sure to purchase measurement tools to get the mixture correct (80/20 by weight). Once I was able to mix correctly the product works good.

Rated 4 out of 5 by from Good product We use the cement to pot small volumes, about 5-10cc. Highly recommend using a vibrating plate to use the cement. Baking to remove excess water is highly recommended

I want to seal the clean out iron hatch to my residential steam boiler. Applying your product like you would a "glazing" compound around a window, to seal the hatch closed. Will this work?

Asked by: Gene70
Thank you for your inquiry. This item could possibly work for this application

Can I mount thermocouples (30 AWG bare wire probes) on a silicon carbide wafer surface? The surface is similar to glass or silicon and the joint must be roughly 5 mm in diameter. Also silicon surfaces are of my interest. Thank you

Asked by: Giorgio AST
Bonding the Thermocouple to the Silicon surface with one of the cements or epoxies would be fine just stay away from the OB-600 which isn't good for smooth surfaces.

Is the cement food safe? I’m wondering if I can use it on the base of a wood fire pizza oven to fill cracks and craters. Will it stand extreme heat? And is a pizza coming in direct contact with it while the pizza cooks okay?

Asked by: Pizzaboss
Thank you for your inquiry. This cement is for industrial and manufacturing use only, and does not have any food safety ratings and should not be in contact with any food. All temperature ratings can be found under the OB-600 specifications on our website.

Could we use this cement to glue thermocouples to stainless steel and use them at high temperature (650 C)?

Asked by: Perry
That would not be an issue.
