Air Set Cements set or cure through loss of moisture by evaporation. Atmospheric conditions therefore affect the drying rate. Air Set Cements are used mainly in thin film applications (applied in thicknesses less than 1/4")*.

SELECTION CRITERIA FOR CEMENTS
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 should 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 parameters are then matched to the appropriate cement.
3. Substrate – What materials will the cement be in contact with?
4. Application Considerations – Pot life, set time, method of dispensing, batch size, cure procedure.
5. Miscellaneous Considerations – Porosity, moisture absorption, electrical resistance, volume stability, clearances/tolerances.

Rated 1 out of 5 by Bree 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 Manu khod 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.
