OMEGABOND® OB-600

HIGH TEMPERATURE CHEMICAL SET CEMENT

INSTRUCTION

SHEET

GENERAL DESCRIPTION

The OMEGABOND®OB-600 High Temperature Chemical Set
Cement is a magnesium phosphate base, one-part ceramic
cement which has many exceptional characteristics
including:

• Resists temperatures to 1427°C (2600°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

OMEGABOND®OB-600 cement is an electrical refractory
cement used where high levels of electrical insulation and
thermal conductivity are needed. It is ideal for potting
applications that are subject to high temperature and/or
thermal shock. The cement provides heavy duty electrical
insulation for appliances, nickel chromium resistance heating
elements, pyrometers and resisters.

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®600 Cement 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®600 Cement 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-600 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®OB-600 cement is a one-part cement and is
supplied as a powder. Weigh out 100 parts of
OMEGABOND®600 powder and 13 parts of water. First
place the powder into a clean mixing container. Then add
water to the powder all at one time while mixing - DO NOT

ADD WATER GRADUALLY! Continue mixing with a slow­speed mixer or with a hand spatula until smooth, uniform
consistency is obtained. Avoid using excess amounts of
water. Excess water reduces the mechanical strength,
increases the amount of shrinkage and delays the setting time
of the cement. Failure of the cement to adhere indicates
setting 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

OMEGABOND®600 cement cures with an internal chemical­setting 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 for
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. The working time of mixed
OMEGABOND®600 cement is approximately 30 minutes when
the powder is mixed with water at 70°F.
