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")*.

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
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?

5. Application Consideration—
Pot life, set time, method of
dispensing, batch size, cure
procedure.

CC High

Temperature

Cement Filler

6. Miscellaneous
Considerations—Porosity,

moisture absorption, electrical
resistance, volume stability,
clearances/tolerances.

Air set cements are also available, see OMEGABOND® 300, OMEGABOND® 400 and OMEGABOND® 500. These cements set or cure through

loss of moisture by evaporation. Atmospheric conditions therefore affect the drying rate. Air set cements are used mainly in the thin film applications
(less than 1⁄4" thickness.)

Porous substrates may require dampening with thinning liquid before application of mixed cement. For OMEGABOND® 600 and

OMEGABOND® 700 (1 part cement), order OMEGABOND® thinning liquid (8 fluid oz), OB -TL. For CC high temperature cement,
use CC high temperature cement liquid binder to dampen porous substrates.
