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.

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")*.

OMEGATHERM thermal conducting paste is a high temperature and high thermally conductive paste product. They are specially formulated for permanent and temporary bonding of thermocouples, thin film RTDs, thermistors and other temperature sensors, to most surfaces metals, ceramics, glass, plastics, paper products.

OMEGABOND epoxy and OMEGATHERM thermal conducting paste are easy to use epoxies and silicone products. They are specially formulated for permanent bonding of thermocouples, thin film RTDs, thermistors and other temperature sensors, to most surfaces metals, ceramics, glass, plastics, paper products. OMEGABOND and OMEGATHERM products are compounded and packaged for convenient, easy mixing and application. Each formulation exhibits important characteristics necessary for accurate, fast, reliable temperature measurement. These are: good adhesion and strength, high temperature rating, high thermal conduction, high electric insulation, thixotropic consistency, fast cure, and easy application.

OMEGA's THERMCOAT KIT is used for cementing fine-gage thermocouples in place on metal, plastic and ceramic surfaces and for assembling and installing thermopiles, temperature probes and thermocouple bolometers.
THERMCOAT CO and THERMCOAT COL This is a fast-setting two-part cement which should be worked at temperatures between 60 and 80F. Work with very small quantities. Once cement has set, it cannot be reworked. Cements mixed too thinly, resulting from an excess of liquid COL, may cause spurious voltaic emfs to be generated in fine-gage thermocouples. Before applying cement, thoroughly clean surface and thermocouples and remove all contamination. Shelf life in excess of 2 1/2 years.
THERMCOAT SL is a heat-curing silicone lacquer used for insulating thermocouples and lead wires. It is useful from -230 to 450F.
