GENERAL DESCRIPTION
The OMEGABOND OB-700 High Temperature Chemical
Set Cement is a sodium silicate base, one-part ceramic
cement which has many exceptional characteristics including:
• Resists temperatures to 827°C (1600°F)
• Resists oil, solvents and most acids (except hydrofluoric)
• Heat conductive and thermal shock resistant
• Excellent electrical insulator
• Adheres to metals, ceramics, glass, porcelain and most
other surfaces
• Excellent mechanical bonding characteristics
• Ceramic-like body
OB-700 cement is used in assembling/sealing applications
that are typical for electrical equipment. It is also ideal for
coating applications on molds and forms that produce special
patterns and shapes. The cement exhibits excellent bonding
characteristics and is used on metals or other materials
which have a high coefficient of thermal expansion.

HANDLING INFORMATION
CAUTION
• Avoid prolonged breathing of vapors - work in wellventilated area
• Protect skin against contamination
• Protect eyes against contamination
• Do not take internally
OMEGABOND 700 Powder is a harmful dust. Avoid
breathing dust by using respirators. Avoid contact with eyes
or skin by wearing gloves and goggles or a face shield.
Wash thoroughly with soap and water after handling. Keep
containers closed.
SHELF LIFE
OMEGABOND 700 Powder has a shelf life of (6) months
when stored in unopened, tightly sealed containers in a dry
location at 70°F.
SOLVENT
A 10% caustic or alkaline solution such as 10% NaOH
(Sodium Hydroxide) will break down the OB-700 cement
after it has cured. However, care should be exercised as
far as the compatibility of the caustic solution with any other
components involved in the application, such as the material
or surface that the cured cement has been applied to.
DIRECTIONS FOR USE
OMEGABOND 700 cement is a one part cement and is
supplied as a powder. Mix the cement by placing 20-25%
water by weight into a clean mixing container. Then gradually
add 75-80% by weight of OB-700 Powder to the water. Use
a slow-speed mechanical mixer or a hand spatula to mix
the cement. Avoid using excess water as that will reduce
mechanical strength, increase the amount of shrinkage and
delay the set time for the mixed cement. OB700 may be
applied by brushing, troweling, pouring, molding or dipping.
If the cement fails to adhere, this indicates that setting action
has begun. In this case discard the cement - do not attempt
to retemper by adding more water. Porous substrates should
be dampened with OMEGABOND® Cement Thinning Liquid
(Part No. OB-TL), prior to application of the mixed cement.
CURING
OB-700 Cement cures with an internal chemical setting
action in 18-24 hours at ambient temperature. Since it is a
chemical-set cement, it can be used in thick applications (i.e.,
it can be applied in thicknesses greater than 1/4"). Cure time
can be accelerated by low temperature oven drying at 180°F.
If the cement is to be exposed to elevated temperatures, cure
at 18-24 hours at ambient temperature, then oven dry for 4
hours at 180°F and for an additional 4 hours at 220°F. This
helps to prevent flaking and chipping.
